I agree with you on most, but that price has been listed for over 2 months..and email have been spread out over 2 months..
I don't want to tell you how to run your business or theirs, but as a consumer, I feel that is plenty of time to update..I think personally
they are keeping old price to suck over customers to their web site..and hook them.
Maybe you should initiate action and tell them their ad(s) are a little outdated, doing us a favor.
