We now over three flat rate shipping boxes from USPS to get your products and gifts to their final destination. While it's not perfect, you can get a lot in a box. It is basically dependent on whether or not you want stashers. The half gallons need the Large Box. The sandwich stashers need the medium and the snack stashers can fit in the small. Worse case pay for the large and we'll refund the difference if we can get everything in a smaller box. Hope this helps!
