Earth's Secret Builds Bigger Wellness Carts with Boost
Earth's Secret makes premium natural supplements in the UK. Sleep Complex built around Affron® saffron for rest without grogginess. Regulate™ Oral Strips for blood sugar. Essentials+ Magnesium with AstraGin® for better absorption. Boost Complex combining Hydrocurc® turmeric, Reishi, Spirulina, and Ginger.
Four products targeting four different parts of a customer's daily routine, and each one pairs naturally with the others. That catalog structure created a real cross-sell opportunity. The problem was surfacing those connections at the point of purchase.
Smart Cart tiers that reward stacking
Earth's Secret uses Boost's Smart Cart with tiered rewards. When someone adds Sleep Complex, AI recommendations surface Essentials+ Magnesium alongside it. A cart reward bar shows progress toward the next threshold - maybe £12 from free shipping, or £25 from a free gift.
Supplement buyers tend to stack products. A first-time customer picking up one formula often upgrades to two or four once they see the savings in real time.
"Full service app that I personally think its the best in the game. Fast support as well :)"

Bundles for daily wellness stacks
Boost's Bundle Builder gives Earth's Secret a dedicated "build your stack" page with its own URL. Customers pick two to five products and save more as they add. Earth's Secret can point email campaigns and paid ads directly at the bundle page. No extra click through a collection page first.
Post-purchase upsells on products that genuinely pair
After checkout, a Sleep Complex buyer sees a one-click offer for Boost Complex. Two-step flow. Accept or skip. Boost merchants see an average 15% revenue lift from post-purchase upsells, and the math improves when the products actually complement each other. Someone who just spent £35 on a sleep formula has already signaled they care about daily wellness.
One app at flat pricing
Running Smart Cart, bundles, post-purchase upsells, and collection filters through separate apps would mean four subscriptions on four billing models. Earth's Secret runs the full stack through Boost at a flat monthly rate.
Support response time mattered too. Earth's Secret brought it up without being asked.
Moneyboard
Boost's ROI dashboard breaks down revenue by feature, so Earth's Secret can compare what Smart Cart tiers generate against post-purchase upsell performance. They track which product pairings drive the most bundle completions and adjust reward thresholds from actual purchase data.
