My take from the conversation was, let's see how much more $ we can get out of this guy. They told me flat out, don't take it if you want, we'll turn around and sell it for more. Other than losing a customer for life with this treatment, in the short term they put you between a rock and a hard place and try to get more profit either way.

I'd let them sell it to someone else and let them know you won't be back.
