Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureAddOnce lets merchants present optional products and services directly on the product page. Create a Companion Product once, then attach it to any product where it belongs. Because AddOnce uses native products, inventory, variants, and fulfillment continue to work as expected. Customers choose optional add-ons before adding to cart, and each item is added as its own native cart line.
Some add-ons aren't optional. Reqmunk requires a companion product — laces with shoes, a warranty with electronics, an install kit with a rack — before the trigger product can be bought. Target products, tags, or whole collections, and write the message shoppers see. The product page gates Add to cart until the shopper picks the companion, then adds both together.
