What gripes me is when the ad says that "you can double your order for free, just pay extra s/h", but then you go to order and you don't have the option to decline the 2nd "free" unit. I bought some uGlu and only needed a small amount for a job I wanted to do. I wanted just to buy the 1 box, but there was no option to NOT take the 2nd "free" box and pay the extra processing fee. That's false advertising. (I'm shocked. Shocked!)
