I had a wonderful experience at Nicks. I brought in two prints for framing and the customer service was top notch (as were the prices). I was immediately impressed when he discouraged me from putting a print in a frame I brought in because the borders would be off. I didn't notice it when I bought it, but he was 100% correct.
He also suggested a really cool mat for the print I did frame. He did it in store while I waited and the cost was great. I would recommend him to anyone needing frames from high dollar art to poster prints, Nick is the man.
