That's why I had "free" in quotes. I think it was about 12 bucks shipping, which isn't great for regular paper printing, but they have strange media print options, so this was just a test to see if they red flag copyrighted material or what have you and if the prints are of a decent quality. I will say that the cardstock is pretty darn thick, so I'll give them that much.
I was thinking down the line, the next time they do a coupon for those blankets or something oddball it might be fun to print some full side art or a flyer or something.
