I recently bought a costco pack of food saver bags because I was out and wanted to use on that night, might not have been cheaper than the stuff from the internet but it was $40 for 3 big rolls (11x50?), one small roll (8x50?) and like 40 medium sized individual bags. That's enough to last me a very long time, so I didn't mind paying. It was on sale for $32 the month before, but I put off buying because I wasn't out yet
