Are there any recommendations for a 3rd party apple vacations discounter?

I'm planning on booking a trip soon and was wondering if anyone could recommend a 3rd party vendor who offers discounts on apple vacations? Specifically the ones who discount the price at 10 or 11% We've already got the resort picked out and it's a return trip so we know what the hotel is like - just a little wary of some of these sites. Thanks in advance!
