Well, I didn't do very well, but if anyone else gets a better promo code, perhaps they might post it. It seems the codes are not unique and can be used more than once. Here is what I got - "You’re entered for a chance to win and your discount promo code has been emailed to you. You can now use promo code SCRATCH10 at checkout to save 10% off an eligible^ vacation package. Choose from hundreds of flights, hotels, rental cars and activities to build a winning vacation package. Plus, when you book your flight with a hotel stay, you get access to discounted flights, unpublished rates and our lowest prices guarantee — and that’s all before your 10% discount... Jackpot! Be sure to purchase your trip by September 30, 2012. "
