Years ago my brother and his wife agreed to a Rainbow demo so that they could get a free trip to Hawaii. They thought there was no way they'd ever consider the vacuum and only agreed to watch the demo so they could get the "free" trip.
Once the guy was in their house though, they fell hook, line, and sinker. It was a really hard sell where the sales guy would not let up. My mom had arrived at their house while the sales pitch was going on. When she saw that my DB and his DW were not doing a good job of saying no to the salesperson, she went into the bathroom and called me to come over quick to talk my brother out of it!
I hung up with my mom and then called my DB and talked to him while I was en route to his house. I had to knock some sense into him about not spending this money that they didn't have (the sales guy was pushing a payment plan). When I got there, the sales guy saw that I was going to talk my brother out of it, so he asked to speak to my DB and his DW outside on the porch. I could hear him telling them not to listen to me and that this vacuum was the buy of a lifetime, etc...
I opened the door and said to my DB, "You will regret this for years. You cannot afford this, nor do you 'need' this thing." My brother finally told the guy no thanks. The Rainbow guy got so mad and used some choice words to tell us off. As he walked away, my brother said, "Hey, what about our free trip to Hawaii?" The guy didn't respond, he just got in his car. I walked over to his car window and said he owed them what he promised. He threw a sheet of paper out at me (as he peeled out) that had an 800 number on it to call for the "free" trip. Turns out the trip was not free at all. The hotel was free, but that was it -- after paying a $400 booking fee and their own airfare!
My DB and his DW were very thankful after the guy left. My brother had this "What was I thinking??" moment and said he just couldn't tell the guy "no."
Maybe they don't do the "free trips" anymore and maybe they do just give the free hotel stays as advertised. Either way, be very careful with these sales people. Obviously they make a HUGE commission off of each sale. I know the OP doesn't want a Rainbow, nor do a majority of the other people who agree to watch the sales pitch, but many end up buying one because the pitch is well rehearsed and is good. For those that really want one, buy one on ebay and save yourselves a ton of money! Skip the sales pitch.
