OK my fellow photo geeks, I have two good US printing deals I can recommend.
First
whcc.com
The site is primarily target toward photog professionals. You have to "become a client" and let them manually add you as a user. However according to a photo blog, the WHCC boss has said they welcome amateur users too.
When I registered they asked me to put in Studio name/size info. I put my the name of a photo studio at one point I was trying to start with a few friends. I am pretty sure them will let you open an account if you let it blank.
Next, they will print 5 free 8x10" fuji luster prints for you as "proofs" to calibrate your monitor. So that was really nice. My landlord lost the first package they ended up sending me a replacement for free. In the package besides the 5 free prints, they also have a tons of print, testure samples and paper samples. I was quiet impressed. The prints was very nice as well. They made my mixbook.com photo books look much worse now.
Second, adoramapix.com
Adorama must just started this venture and they have nice promotion.
If you open an account, go to bottom of your page and refer a friend, both your friend and you can get $5 credit. I just open one for me and one for my wife. The beauty is that they let you use the $5 credit on your first order so you if you are getting small run of prints you practically don't have to pay anything.
I haven't figured out how to use the credit to buy frames yet. It seems to me adorama and adoramapix.com catalogs are separated.
