Thanks. We stopped by the Southcenter Kinko's (S. Seattle, WA) last night, but they didn't know anything.

What paper stock do you use? And at what size do you start thinking about foam core?

If your local Kinko's can't help, check your Yellow Pages for sign-makers and independent printers. They should be able to give you prices based on the size of the end product. Ballpark figure for a poster size would be around $20.00 - $50.00, (It depends on your local economy.)

I've never made a protest sign (I think it's time to start, though). But I would compare the cost of printing to a foam core versus printing to regular poster paper; seems to me it might be cheaper to pay for the poster, and get the foam core at Walmart along with some glue, and stick the poster to the foam myself.
