It seems that the whole problem with this is that their promise is not valid in most cases. As indicated, if they said something like, "order a vacation and we'll give you up to $1100 back" that would have been better (although still deceptive.)

I should try that for my small business:

Buy my product and get free shipping(*)
(*) up to 0.01 per order, applied as a credit on your next order.

As for "based on double-occupancy", many hotels say this but don't really charge you extra...unless they're resorts.

Is it any wonder that people have come to distrust all businesses, no matter how trustworthy they are?
(If you run a legit business, people nickel and dime you to death; if you falsely advertise, they accuse you of misleading them--and rightly so!)

Anyway, I feel bad for travel-related businesses, but it's time for them to find a new business model to get people to their resorts/countries/etc. For example, why are Mexican resorts more expensive than U.S. resorts when the taxes are much lower, the food costs are much lower, and the labor costs are much lower? And now they're complaining because the world's economy is down and they're not getting the same hundreds of millions of dollars per year that they used to.
