How This Supplement Brand Hit 4.5% CR With Gift Offers

Most supplement brands run promotions with one vague goal: sell more. High-growth brands are more intentional. They make each promotion work toward specific business goals, from increasing AOV to building recurring subscription revenue and driving adoption of new products.

Turmeric Australia turned this strategy into real growth, lifting its conversion rate by 4.5%. The brand smartly paired free gifts with purchase with volume discounts and subscription products to make them convert effectively.

In this case study, I’ll break down how Turmeric Australia set up these offers, the business goal behind each one, and why they work particularly well for health and supplement brands.

TL;DR

• This offer strategy helped Turmeric Australia achieve a 4.5% conversion rate, 36% higher than the Health & Wellness industry median of 3.31%.
• Choose a promotion app based on reliability and proven performance, not just features and pricing.
• Pairing free gifts with volume discounts lifts both AOV and conversion rate.
• Gifts that fit naturally into a supplement routine make the offer have higher perceived value.
• Instead of offering a single percentage off, use the frame “Buy X get Y free”. Both offer the same discount amount, but the latter helps to increase sales volume.
• Pairing gifts with subscription products makes recurring plans more attractive.

The Challenge: Achieve Multiple Growth Goals Without Risking Customer Trust

Growing a brand in the supplement space, where customer trust is hard to earn, acquisition costs run high, and results take weeks to show, requires more than running a single type of promotion on repeat. 

Like other supplement brands, Turmeric Australia needed to achieve multiple business goals at the same time, each with its own constraints.

Three key challenges stood in the way:

• Grow sales without deeply cutting prices: Supplements are a trust purchase. A deep and too frequent discount can make shoppers question expiry dates, ingredient quality, or whether the brand is clearing unwanted stock.  
• Turn one-time buyers into subscribers for recurring revenue: Acquiring customers is relatively expensive in the Health & Wellness category, with a median CAC of $72.66 according to Polar Analytics’ ecommerce benchmark, making repeat revenue especially important for sustainable growth. 
• The previous promotion app was unreliable: Frequent bugs and limited offer support made it difficult to run the setups the brand needed. Turmeric Australia needed a reliable app that could seamlessly manage multiple offer types across a large catalog.

That led the brand to BOGOS: Free Gift Bundle Upsell, a trusted promotion app used by 95,000+ Shopify brands worldwide over the past 12 years.

BOGOS has processed billions of orders for high-volume Shopify stores while maintaining fast site performance and consistent functionality across devices. 

The Solution: Layer Free Gifts With Volume Discounts 

Turmeric Australia’s main strategy was to layer free gift offers on top of volume discounts, giving customers suitable reasons to buy more.

BOGOS feature used	Offer used	Value for stores
Free gift + volume discount	– Offer 1: Buy 6 Moringa Leaf Capsules (pay for 4, get 2 free), get a free pill box plus a free cookbook. – Offer 2: Buy 6 Curcumin Gol (15% off on total order), get a free pill box plus a free cookbook	Increases basket size while protecting the product’s price anchor
Free gift	Buy any of three combos, get a free pill box	Nudges shoppers from a single bottle to a higher-value three-bottle combo
Free gift plus subscription subcondition	Buy any subscription product, get a gift set of a pill box, a zip bag, and a cookbook	Converts one-time buyers into subscribers
Free gift	Buy 1 Harmony Plus, get 2nd bottle at 50% off	Expands product adoption and encourages repeat purchases

#1. Layer free gifts onto volume discounts to increase AOV

Instead of relying on a flat percentage discount, Turmeric Australia layered volume buys with free gifts. Shoppers who bought a set quantity could unlock extra bottles for free or receive a percentage discount, plus a free pill box and cookbook automatically added to their cart.

Here’s how each offer was set up:

• Offer 1: Buy 6 Moringa Leaf Capsules (buy 4, get 2 more free), get a free pill box + a free cookbook 
• Offer 2: Buy 6 Curcumin Gold get 15% off + get a free pill box + a free cookbook

This setup serves two business goals at once: maximize AOV for hero products and improve conversion for slow-moving products

The key is not giving every product the same deal, but adjusting the incentive based on how each product is already performing.

Maximize AOV on hero products with a lighter incentive

Curcumin Gold was already a strong seller with 100+ reviews, so Turmeric Australia kept the offer relatively light: buy 6 and get 15% off, plus free gifts.

Since shoppers already had a reason to buy the product, the discount only needed to nudge them toward a larger quantity. The goal here was less about winning the sale and more about increasing order value.

Lift conversion on slow-moving products with a stronger incentive

Moringa Leaf Capsules had no reviews and needed a bigger push, so the brand offered buy 4, get 2 free, plus gifts.

This gives shoppers the equivalent of about 33% off the six-unit retail value, but frames the savings as extra product rather than a markdown. The full unit price stays visible while shoppers feel they are getting significantly more value.

Encourage consistent use and potentially faster reorders

The free pill box helps shoppers organize a week’s doses and makes consistent supplement use easier. For products designed for regular use, better adherence can also mean customers finish their supply on schedule and return for their next purchase sooner.

#2. Use a relevant free gift to naturally encourage shoppers to buy a combo

The second offer takes a different angle from the previous one. Instead of discounting individual products, it targets selected three-bottle combos, including two best-sellers: Organic Turmeric Capsules and Viraguard.

The offer was: Buy an eligible combo and shoppers get a pill box for free.

The promotion mechanic works for three clear goals:

• Increase AOV with a relevant gift: A pill box fits naturally into a daily supplement routine, giving shoppers a stronger reason to move from a single bottle to a three-bottle combo. This can lift AOV by roughly 2.5 to 2.7 times.
• Support repeat purchases: By making daily use easier, the pill box can help customers stay consistent with their routine and support a more regular repurchase cycle.
• Use the free-shipping threshold as an extra nudge: The Organic Turmeric three-bottle combo costs AUD $94.95, just $5.05 below the $100 threshold. Moreover, BOGOS’ progress bar makes the free-shipping incentive visible in the cart drawer and shows shoppers exactly how close they are to unlocking it. This gives them a clear reason to add one more item and slightly increase the order value. 

With this setup, Turmeric Australia combines two strong AOV levers: a gift that naturally complements the product and a free-shipping threshold that effectively nudges shoppers to add one more item.

#3. Tie A Welcome Gift to Subscriptions To Grow Recurring Revenue 

While the first two offers focus on growing the size of a single order, the third offer shifts the goal to long-term value.

Turmeric Australia targeted this offer on subscriptions only: buy any subscription product and receive a free Welcome Gift set with a pill box, zip bag, and cookbook. 

Recurring revenue is something every supplement brand cares about, because subscribers carry a higher lifetime value and a lower churn rate than one-time buyers. Two details make this offer land: 

• The gift set supports the full routine: the pill box helps with daily dosing, the zip bag makes it easier to carry, and the cookbook adds extra lifestyle value. Together, the three items read as a complete onboarding toolkit rather than a single token item.
• “Welcome Gift” makes the subscription feel more valuable: Instead of feeling like another promotion, the gift makes subscribing feel like joining an ongoing program with an extra benefit from day one.

What makes this offer work seamlessly without logic conflicts is BOGOS’ subscription sub-condition. 

It ensures the free gift is automatically added to the cart only when shoppers choose a subscription product, keeping the offer logic clean and the buying experience smooth.

#4. Use a strong second-item discount to grow a newly launched product    

Harmony Plus is a relatively new product in Turmeric Australia’s catalog, so it has less recognition than the brand’s established supplements. 

To attract more shoppers and expand its market, the store uses a strong incentive: buy one bottle, get the second at 50% off. 

The offer does more than lift AOV. It lowers the barrier to trying a less familiar product while giving shoppers high perceived value and a longer trial period.

That matters for supplements, where results often take weeks or months of consistent use. A half-price second bottle gives buyers more time to experience the product without paying full price. If they see results, they have a stronger reason to repurchase later.

The Results: Conversion Rate Steadily Reached 4.5%

After launching these offers, Turmeric Australia’s conversion rate steadily reached 4.5%. That is around 36% higher than the 3.31% Health & Wellness industry median, showing that the improvement was not just a short-term promotion spike. 

The result highlights two tactics that worked especially well for this supplement brand:

• Layer free gifts with volume buys and subscriptions 
• Choose gifts that naturally complement the original products

For supplement brands, the takeaway is clear: don’t rely on discounts alone. Layer free gifts with volume buys and subscriptions, and choose rewards that complement the core product to lift AOV, grow recurring revenue, and protect brand trust.

Reliable execution also mattered. After struggling with a buggy promotion app, the brand moved to BOGOS: Free Gift Bundle Upsell for consistent offer performance, backed by a support team with over 12 years of Shopify promotion experience. 

Conclusion

Turmeric Australia shows that a supplement brand can grow sales by layering free gifts with volume buys and subscription offers, and choosing gifts that naturally complement the original products. With this approach, the brand steadily reached a 4.5% conversion rate. 

If you sell supplements or any routine-based product, apply the same logic and see whether this strategy can become a game-changer for flat sales performance.
