I saw this deal early this week but I wanted to wait to confirm it worked before posting. Right now there is a $5 off coupon on Target.com for Kodak cameras. The disposable Kodak cameras are priced at $4- so you should be able to get them free! Keep in mind some cashiers might give you a hard time with this one. You might have a copy of the coupon policy on hand which states that they can adjust the coupon down to $4.
Thanks Coupon Geek!
