I'm subscribed to several Groupon-like services, and it seems that maybe 75% of the offerings I get are similar to this - skydiving, drive a Ferrari, race car driving course, spend a night at a fancy castle and drink champagne for breakfast, those type of things. I guess there's a market for them, but I wonder why those types of products are so prominent in the offerings here in the Netherlands.
