The price tags come on a 8.5x11 sheet, just like address labels. A stack arrives (monthly? Weekly? Not sure) from corporate in an envelope. I'm not sure what happens when the tag gets lost; fortunately those are usually the handwritten signs falling into carts. Price tags really should just be printed at the store.

I doubt if most price tags last more than a month at clothing stores, maybe a year at grocery/other large chain stores. Department stores and trendy fashion stores have too many sales and don't keep the same items in stock year round anyways.
