I wish I could tell you how to get this but I'm afraid the title is a bit misleading. I've always been told you can only use one rewardzone cert per transaction, apparently thats just a dirty lie so I decided to cash in my points. $70 in rewardzone certs, tax (), and shipping (too much) means $18 shipped. Not bad! Just wanted to express my happiness. It'll be nice to replace the easily-dirtied acrylic one that I've been using since I got rid of my iMac.
