What this video covers
Every setting on the Create Build-A-Box page for a Fixed Pricing Bundle, one price for a box whatever shoppers put in it: the Build-A-Box Name, Allow One-time Purchase, the Subscription Plan and its parent products (Configure now, Add Parent product), Min Quantity and Max Quantity, Selling Plans, Child Products, Clone, Delete and Quick checkout link. Then Advanced Settings (Select Bundle Redirect, Sync Child Product Inventory, Choose Products Text, Top Custom HTML and Bottom Custom HTML, Button Label) and Build-A-Box Status. It ends on your store, in the cart and in the customer portal, where customers can swap a coffee or edit their box.
In short
Create the box as a product in Shopify and add it to a subscription plan first. In Build-A-Box, click Create Build-A-Box, name it and choose Fixed Pricing Bundle.
Each product of the plan you pick is a parent product, a box with its own price. Min Quantity and Max Quantity set how many items go in it (an empty max means no limit); Selling Plans left empty offers all the plan's delivery frequencies.
Tick the Child Products shoppers can choose from (draft or archived products don't show on your store). Clone copies a box's quantities and products to another product in the plan, for a second size. Drag the rows to change the order of the boxes on your store.
On Advanced Settings, Select Bundle Redirect sends shoppers to the cart or to checkout, and Sync Child Product Inventory (under Inventory Options) adds each shopper's picks to their Shopify orders. Button Label only works on Dynamic Pricing boxes: change a Fixed box's button texts in Customize Build-A-Box.
A new box starts as Disabled: choose Enabled and click Save, then use Copy link or Access Build-A-Box in the list. In the customer portal, subscribers can Swap an item or click Edit to change what's in their box.
