Say, frozen chicken, napkins, instant noodles, paper cups, etc. In some cases there is only 1 option offered, sometimes 2, rarely are there ever more than 4 options offered at Costco for a single type of item. When you trust that you are being offered the best choice or a top choice, well, we know what happens at Costco. People buy pallets in that warehouse.
