Questions
What is a kit?
A kit is a mix-and-match offer on its own page. You choose a set of products and how many the shopper must pick, for example "pick any 3 snacks". The shopper picks, sees a progress bar, and adds the whole kit to the cart in one click.
Does it work with my theme?
CRO Booster uses theme app blocks, which you add in the Shopify theme editor. It does not edit your theme code. If you remove a block, it is gone cleanly.
How are discounts applied at checkout?
At checkout the bundle items are merged into one bundle line with the discount, using Shopify's own checkout (Shopify Functions). No discount codes are created.
How much does CRO Booster cost?
The Free plan is $0. The Pro plan is $4.99 USD every 30 days, with a 3-day free trial. Shopify bills it, and the charge shows on your Shopify invoice.
