Design a Bulk Bag with available compartments for every main food category that can be purchase in bulk at a supermarket like Whole Foods or other. Each compartment could be clipped to the inside walls of the Bag to adjust for different needs. Overall, it is the lunchbox idea transferred to grocery shopping, where the bag helps make bulk shopping easier, all organized in one place. The Bulk Bag would have the Twin Bulk Bag so that at the cashier, after the inserts are scanned and weighted, they can be placed inside the Twin Bulk Bag.
Partner with Bulk Markets to allow the Bulk Bag to be used without the inserts having to be weighted before hand.
The picture above is an idea of what the inside of the bag would look like.
