FAQ
Questions about Breakly Bundles
Does the kit price match at checkout?
Yes. Breakly Bundles prices kits through Shopify's checkout, so the total in the box is the total in the cart and at checkout.
Can shoppers pick variants inside a kit?
Yes. Each piece keeps its own size or color, chosen in the box before it goes to the cart.
Will it work with my theme?
It adds itself with an app embed or a theme block and reads your theme's fonts, colors and corners, without code edits.
Can I use it with Breakly quantity breaks?
Yes. Use Breakly for multi-buys of one product and Bundles for sets of different products; the discounts don't fight over the same line.
