Why Does Camping World Advertise Items they don't have?

I just sent a PM to someone from CW via this posting.

I still haven't heard any replies other than the response to this posting from CW.

Now I realize how lucky I was not to have purchased our new RV (earlier this year) from CW.

With online retailers stomping on each other trying to get our business, does it make any sense to deal with a company with very poor customer service?
