Your customers don't know which supplements work together. They buy one protein powder and leave. A guided bundle with compatibility rules and subscription pricing turns one-time buyers into recurring revenue. Smart rules prevent bad combinations while tiered pricing rewards loyalty.
Compatibility
Product compatibility rules
Already selected Creatine? Don't show the Creatine + Beta-Alanine combo (redundant). Selected a stimulant pre-workout? Hide the stimulant-free option. Rules that prevent bad stacks.
