Those acrylic holders get to be a bit expensive when talking about quantities in the hundreds. A 5X7 runs $2-$3, while larger sizes run upwards of about $5 each.

Would a tabletop tent like you find in restaurants (Big Boys comes to mind) advertising deserts and such be a better way to go? Haven't had any luck finding these online so I don't know what they would run. Or would this be something you'd find at a print shop?

What are those anyway, laminated, high gloss card stock, or light weight display holders?
