I get mine printed here: http://www.perfectposters.com/
They are fantastic to deal with. I had one come in that the corner looked like it got wet, and cringed at having to buy another. No problem, he sent me out another one no charge. Cant say enough good about them.

I find that Costco does very good prints, not sure about all Costco's , It have to do with the person that is doing the printing. When I get prints done I do the corrections, have them turn off the auto correct.
they are an excellent service that offers many printing options and i have never seen an equally good print.
they will do panoramas in everry possibly imaginable format and their service is also quick and reliable.
given that it is a professional service also employed by many art gallerys it will reflect on the pricing, however given the excellent quality, they are hardly expensive.
In my area they have 2 Costco locations. One will match my lab color prints at least 98% while the other will be totally off. I don't mean a little but the exposure is different and so is the color. I suggest a test print first but then again costco does not make youkeep anything you are not happy with.
