Upload & Sell: On
My wife and I participated in one of those "crafter's coops" for a year. We never sold enough to pay the monthly fee, much less to make a profit. But your milage may vary.
I repurposed the mats and frames from my show toward other print sales. Having the precut mats and frames on hand allowed me to sell other, custom prints for less money.
Coffee house shows are a bit of a crap shoot because so much depends on the demographicsof the people who go there. The coffee house where my show was caters to students from the nearby university, who don't spend money on photographic prints for their walls
But at night, it hosts many music events, and they attract the crowd I wanted to reach with my pictures.
