I see a lot of collectors keeping their game-used jerseys and similar items hung inside those clear plastic garment bags, like suits come back from the drycleaner's in. Only...where can you buy those bags in quantity? Or, for that matter, at all? Can you buy, like, a hundred of them at a time, from some drycleaner supply outlet? I've got a closet full of jerseys that I really need to start preserving better.
