I need 16 total sets of photo's... cheapest place to develop them?

[PoPPeR]

I have two disposable camera's, and I need 8 total prints from each camera (took a trip with friends, everyone wants a copy). I went to Longs Drugs, and it costs 8.99$ for overnight service with free double prints, but the 6 extra prints from each camera cost even more then it would to develop 6 more camera's... something like 35 cents per extra picture. Where should I go to get 16 total prints from 2 disposable camera's?
