When you’ve loaded your cart with a Super-Jumbo package of toilet paper, a pallet of canned cat food, the New Bonus-Size! can of tomato juice, three 25-lb. sacks of kitty litter, and seventeen other super-sized containers of consumer goods, remember this simple fact: The Humongous Warehouse Conglomerate Cleverly Marketed As A Down-Home Corner Grocery Store© does not take your MasterCard.
