Those little Back2School items are handy. The pens are .33 and it's nice to keep one on my keychain so I can write the amount on my free coupons. The cashiers love it when I do that.
I went to a CVS recently and told the guy behind the counter (shift manager) that I knew I had some ECB coming to me. He scanned my card, scanned a magazine, then vioded the magazine and ended the transaction. No purchase necessary and I got my ECB. He says he does that for himself too when he has ECB coming to him.
