Often people will go in search of coupons on the internet before they go on there trip. Be careful of this! Often the coupon you buy on the internet are the same one as you would get for free when your in Vegas. I know on "Ebay" there are a lot of people selling 2 for one coupons. These same coupons you can get for free! There are several free books and pamphets that have the same coupons in them...... eg. "Vegas Valves" coupon book. Don't get me wrong Ebay is a great source for great deals sometimes.... Just make sure you do some homework before you buy. I have seen lots of great Vegas coupon deals on ebay that don't take advantage of people. Hope this helps. Take Care
