Start21 Mix & Match Bundles

The app is presented as a mix-and-match bundling tool for merchants selling apparel and other variant-based products. It lets shoppers build offers like “any 2 for $45” by selecting the exact product, size, and colour for each item in a bundle, while keeping checkout, orders, and inventory tied to the chosen variants. The description emphasizes automatic inclusion of new sizes and colours in bundles and easy theme integration through a block, but there are not enough reviews to analyze right now.
