I'm sure this varies a lot depending on the competence of the people who run it and the condition of the machine. In my area, a local CVS has a Noritsu and a local Walgreens has a Fuji. The Walgreens produces much better prints. The prints from the CVS's Noritsu, whether they originate on film sent through their C-41 line or digital images I deliver, come out with a ghastly cyan cast and a "streaky" appearance that I associate with an inkjet cartridge that's on the verge of clogging up. (I don't know if the machine actually uses inkjet technology; it could be something else that just looks similar.) The Walgreens prints, although a bit high in contrast when they do the scanning, have decent color balance and a much smoother appearance. I also prefer the Walgreens prints because they're made on Fuji RA4 paper, vs. whatever non-RA4 technology the Noritsu uses. Therefore, if I get prints at Walgreens, I'm at least driving a small amount of demand for RA4 paper, which can only help long-term availability of same for my own use in my own darkroom.
