Printing Photos for Exhibitions

I've been printing photos for local art exhibitions for the sale of my work. I've found Shutterfly (with my Costco membership) has been very help for timing and professionalism. The matted framed prints look very good. But I'm debating if there might be better avenues I should look at. The cost to do a 16X16 matted and framed is $169 and with my artwork running around $600 it eats into my margin quite a bit with the gallery's commission.

Any suggestions on better quality and or price?
