The hacks
Complete-the-stack bundle below the hero supplement
Below the protein powder: "Complete your recovery stack" with BCAA + creatine at a bundled price. The stack logic makes every additional supplement feel necessary.
Tiered stack builder on the product page
"Just this supplement ($34)," "2-product stack ($59, save 13%)," "Full goal stack ($85, save 17%)." Tiergain embeds tiered stack options directly on any supplement product page.
30/60/90-day supply selector on the product page
30-day: $34. 60-day: $62 (save 9%). 90-day: $85 (save 17%). The selector directly on the product page shows savings before add-to-cart. Most customers pick 60 or 90-day.
Goal-based bundle recommendation on each product page
On the magnesium page: "Part of our Sleep Stack. Add melatonin and L-theanine for the complete sleep goal." Goal framing makes the stack feel prescribed, not suggested. Tiergain structures goal bundles per product page.
Free trial-size threshold shown on supplement pages
"Add $21 more to get a free trial-size of our new collagen blend" below add-to-cart. The trial introduces the next SKU while lifting the current order value.
Post-purchase subscription conversion from product page buyers
Bought the stack from the product page? Offer auto-ship at 15% off recurring. The customer just built their stack. Converting to subscription while they feel committed pulls 11%.
Every supplement product page should show a stack, not just the bottle
Supplement buyers think in stacks. Your product page should show "Part of the Energy Stack" or "Completes the Sleep Stack" on every single product. The stack context drives multi-bottle orders from day one.
