I use a binder. Shock, huh? LOL... I have a binder full of sheet protectors. In each one I have a piece of coloured paper (just to make it look pretty), each page is a different store. It's basically my rebate folder, so the first page is my table of contents, the next is rebates in queue, then the stores in ABC order, categorised by type of store, then I have an "extras" page. That holds rec't for places I don't shop at often. Any rec't's for large purchases get stapled to the instruction manual & those are all kept in a file in my file cabinet.
