Hi @nikkijb 
Based on your requirement to create a meal deal where customers pick 1 item from each product group (burger/fries/drink) but the entire combo is charged at a fixed price (e.g., £5), while the individual items inside still have their own different prices, Easify Box Builder can fully support this - exactly as shown in the demo I built above.
Here’s an example I’ve created so you can see how it works:
Currently, the Easify Box Builder app offers four different box types, and for a fixed-price meal deal scenario like the one you described, Predefined Box Sizes is the most suitable option.
Specifically, Easify Box Builder lets you create a dedicated bundle page where customers build their combo through clear step-by-step selections—for example: Step 1 choose a burger from the Burgers collection, Step 2 choose fries from the Fries collection, and Step 3 choose a drink from the Drinks collection. In each step, you can specify that customers may select one item, and all of these selections will be grouped together into a single box.
With this box type, the Discount & Subscription section acts as the “Choose Your Box Size” step in the shopping experience. You predefine a box size with a fixed number of items (for example, 3 items) and assign a fixed price to that box (for example, £5), completely independent of the individual prices of the products inside.
From a technical perspective, you simply need to create a new box in BB, select Predefined Box Sizes, set the box size to 3 items with a fixed price, and then add the corresponding collections for each selection step. The products will keep their original variants, images, and information from Shopify, but when they’re included in the box, the system will calculate the price based on the box price, not by summing the individual item prices.
Easify Box Builder is extremely accessible, thanks to its simple interface and fast onboarding - you can be fully set up in minutes, no technical background needed.
