Where CartHook Falls Short
Post-Purchase Upsell, Not Pre-Purchase Architecture
CartHook shows offers after checkout is complete. It does not build the shopping experience before checkout that structures the initial order with bundles, tiers, and progressive rewards.
No Bundle Builder or Cart-Level Offer Stack
CartHook manages post-purchase funnel pages. It does not create tiered bundles, mix-and-match flows, or combined discount + shipping + gift rewards during the shopping journey.
Post-Purchase Adds Single Items. Pre-Purchase Builds Multi-Item Orders.
CartHook adds one product at a time after checkout. Tiergain builds 3-5 item bundle orders before checkout. The structural difference means bundles drive larger initial orders.
Revenue Share Pricing on Post-Purchase Sales
CartHook charges a percentage of post-purchase revenue on top of the monthly fee. Tiergain charges flat monthly pricing regardless of how much bundle revenue is generated.
