Most of the drug stores, Wallgreens, Bartells etc have film.

I just bought color and BW film last week for my early 80's vintage Canon A1. The daughters in a fhotography class and she is using my digital along with the schools DSLRs, thought she needed to take some photos with out the instant image.

Pictures came out as good or better after developing, mostly luck, but it was amazing. I have some old lenses with really good Fstops and she took some excellent depth of field shots.

The old A1 is pretty much a paper weight now, but it was fun.
