Free Samples

In yesterday's mail I received a small yellow envelope with free samples! While exploring the internet for drywall options to use behind shower tile I stumbled across Georgia-Pacific's online offer for free samples. What could it hurt? Click a few buttons and a poof(!) I've got options in my hand. I'm not sure I really needed the samples or what I'm going to do with the postcard size pieces of gypsum, but it is neat to see/feel the difference between paper faced green board and acrylic coated glass matting. I suppose I could subject them to a barrage of testing... or cut them in half and make coasters:)
