Have used SkyAuction for several trips to Caribbean with great success. Currently have trip to Belize in January on Continental from Boston through Houston. Got the flights I wanted at a very reasonable price. Just went to LatinDiscounters.com to compare and SkyAuction prices were about $75.00 less. As with any flight, I think the further out your flight is, the better your chances of getting the flight/seat you want. The caution about credit card is well taken. I think that in the very near future all credit card companies will be using "smart cards" to prevent this sort of thing. Another caution about SkyAcution...it is an auction and you have to avoid being caught up in the "excitement" and forget about how much you're bidding vs. what that trip will cost you elsewhere. Good Luck!
