For a few years now, I've used Fotki.com to store and host my photos. Its a steal - super cheap and no storage limit. Until the other day, I had not ordered prints from them - or anywhere else, for that matter. Well, the four samples I decided to order arrived today and I am quite impressed! Particularly with the B/W ones. I ordered a few different sizes, the largest being 11x14, and they were all great. I haven't shopped around but I believe their pricing is pretty cheap also.
So if you're in need of prints, I definitely recommend using Fotki.com!
