The site is a great idea, but don't expect to receive many items anytime soon. I have $250 in gift cards, and it has been well over 2 weeks and I have not received them. I did receive my ice cream maker and $15 itunes card quickly. The $250 items were won on a Wednesday, and the following Thursday I won the itunes card and Ice cream maker. I receved those two items in about a week, but have not seen any of the Lowe's $250 gift cards.
My thoughts are that the site is hurting for money, primarily cash flow, and they are using delaying tactics to stay alive during the recession. Be careful! If they go out of business, you will not receive any of your products.
