I've used dotphoto to print scans of some black and white wedding photos and other color prints. If you are printing a lot of black and white photos, send them as a separate order. They use a color process for their printing and when you have a mix of B&W and color, it's not pretty. I ended up returning prints two different times but in the end they got it right and gave me a credit for my trouble. I think their customer service is good--responded to my requests promptly. They have run a sale the last two months for free shipping over $25 but I haven't seen an offer for October yet.
