Bundles or Kits

The ability to have automated bundles is a fairly simple, but effective way to increase sales.  The option to add an item that is connected to other items in your booth that updates based on sales is a common add on in inventory management systems, but no storefront offers the option at this time.

Examples of how this is useful.

You sell individual packs of incense, but want to offer the retail box as well.  You have a listing with the individual pack and add a bundle of 12 individual packs for the retail box listing.  Anytime a Retail Box sells, it reduces the individual packs by 12, conversely if a single pack sells it updates the retail box quantity to reflect how many full retail boxes are available (so if there are 23 single packs left after a sale, the retail box listing would reduce to one as that's only one full retail box)

A bundle that combines a pillow, pillow cover, and carry on bag for mobile use.  The individual listings would each be available and the bundle would include one of each of these items.  Any sale of an individual item would change the bundle listing to be equal to that of how many full bundles can be filled with the remaining inventory, a bundle sale would reduce each individual item by the amount of that item included in the bundle (in this case one)
