We got 1000 cards printed and paid extra for blank back and the medium shipping service (what, a week or two?). Turned out to be around $32 or so. Cards showed up after almost two weeks. Looks decent. Yeah, $5 for 250 cards is cheap, but if it's for business use it's worth the money to pay for a blank back. In comparison, the cards that we had before, made by a local printer, cost over 4x as much per unit, and we had to buy more at a time.
