If your interest is to have substandard photo printing, Presto Photo can surely provide. If you want sub-par customer service, Presto Photo is there to make sure you aren't treated properly. If you want your stellar photographic images to look like trash once printed, well, Presto Photo is ready to deliver their useless "service" and take your money. For anyone else that is seeking even the slightest bit better than Presto Photo your next stop could be to any WalMart, Walgreens, or other non-photographic cheap printer.
I've worked with many print companies quite satisfactorily and thought to give Presto Photo a try as well. What a huge mistake that turned out to be. The quality was horrific. The images they returned were paled, invoked a green hue, and are completely worthless. Contacting the "customer assistance" was even more distasteful as they were basically non-responsive (email every OTHER day), clearly didn't have any knowledge about photography or the printing process, and were not interested in any resolution. After more than a week it has finally become clear that I will have to take up action with my credit card to ensure that I'm properly refunded.
So just a word of warning... DON'T. That's right, don't use Presto Photo. Save yourself the hassle, the grief, and your eyes from having to see the terrible effort they give on your images. These clowns don't deserve to print junk mail fliers let alone photographic prints.
