MixMaxer gives you one wizard for volume discounts, fixed bundles, Buy X get Y and free gifts, bought-together suggestions and mix and match sets. Offers appear through theme app blocks with no code edits, and discounts apply in checkout and Shop Pay without stacking twice on one item. Every offer can be A/B tested: visitors are split, each pays the variant they saw, and the winner can be applied automatically. Profit uses your cost per item; a holdout group shows the true uplift.

• Volume tiers, bundles, BXGY, free gifts, bought-together and mix & match sets
• A/B test any offer; the winner can be applied automatically at your confidence
• Profit per offer and per variant, read from your Shopify cost per item
• Holdout group measures the true order-value uplift of all your offers
• Discounts apply in checkout and Shop Pay; nothing added to your theme code
