So for anyone thinking ahead to the card exchange or just thinking about the holidays, Groupon has a deal for 5"x7" cards from Zazzle right now. 40 cards for $25, 75 for $35 or 110 for $45. We used this deal for ours last year and were pretty happy with how they turned out. Nice quality, I just didn't like the design interface as much, no super user friendly. But eventually figured it out!
