Go to walmart.com to view the BF ad. If you click on the "1-Hour In Stock Guarantee" area of the ad you will find the terms of service. Here's a few of the terms....... "Payment must be made upon checkout for the Guarantee Card. Deadline for payment may vary based upon local store hours-see local store for details". "Merchandise will be delivered to the same store where the Guarantee Card was purchased." "Customers will receive notice via email when the item has been shipped and is available for pickup. Valid email address is required." "Guarantee Cards must be registered by 11:59 CST, Sunday, Novemeber 25, 2012. If not registered during that time the Guarantee Card will become a standard Walmart Gift Card loaded with the amount of Black Friday item purchase price" "If Walmart is unable to fulfill your order a full refund will be provided upon request. A comparable substitution may be available." Hope this answers some of the questions!
