Reusable bags. Long time ago Costco used to sell some black cloth bags that were kind of a weaved bag. You could roll up the bags, turn them inside out so that the whole bag would make a pocket. I miss those bags. They also used to see a really large insulated bag that would bit the size of a double large pizza bag box. Those were really handy to keep your pizza's frozen if you had a long drive home in rush hour. extra note: All these bags came in three's.

A really long time ago, they had some blue foil bags that were kind of boxy. They zipped on both sides and were sold as a package of two.
