Have you ever sat through one of those time share pitches?  I've had the privilege of sitting through several in my life time and each one wraps up with a clear message-  "BUY NOW".  Time share sales folks want you to sign up before you leave.  They know that if you leave the presentation and think it over you probably won't be back or you might go look at a competitor.  They wouldn't sell many time shares if they gave you a big sales pitch and never asked you to buy, but that is just what a lot of websites do.
