When I was a Girl Scout (like forever ago) I asked my drunk neighbor if he wanted cookies. He bought 32 boxes.

6 boxes of Thin Mints, 7 Caramel deLites (Samoa's), 5 Peanut Butter Patties (Tagalongs), 4 Peanut Butter Sandwiches (Do-Si-Do's), 1 Lemonade, 1 Shortbread (Trefoils), and 1 Thanks-A-Lot
Should hold you off for a bit.
