I read these posts and all I can think of is the South Park Cartoon episode where the parents of all the kids are getting the Major Hard Sell to buy a time share in a ski resort. No matter what they do, they keep getting sucked back into the room with the salesmen.
Years ago, (1982) I filled out a chance at a 1 month membership for a gym. Of course, "I won"...Once we got there, it was a gym in a strip mall. Very few machines, no "lap Pool" as described in the ad (to be added at a later date)...When we finally got the sales pitch, They wanted $899 a year for one member and only $450 a year for the additional member...I had just graduated from HS not 6 months prior. Needless to say, We got up and walked out of the office, with the lady trailing behind offering all kind of promises.
As probably stated in the other posts, if the offer looks too good to be true, it is.
