I agree. Send then with insurance and delivery confirmation or certified mail. That is unacceptable. I can't believe they think they could get away with that.I Furthermore, if you ordered them before the switchover on 1/2 which you did, you should have got the regular hoppers. Right there could be your out with the Credit card dispute. They did not actually send you what you paid for which is different than just sending them late. When you fill out your dispute resolution with the CC company be sure you put that in first and foremost stating you bought one advertised item and recived something else, as well as it taking loner. When you pay for one thing and get another that is easy to dispute, and Hotwire will have a tougher time proving they are in the right.
