the disposable cameras they sell do come with flash. but there's a little button kind of thing to activate the flash, so that there'll be a flash, so i think you can use it w/o the flash if you don't press the button thing on the front before each picture. they cost $15 (or at least at the Bryce Jordan concert). i didn't have too much of good luck with my three cameras. since only about 6 pics out of around 80 something onely came out somewhat. Oh well, i've learned to love them!
