Something strange at Walmart.com

[ibeetle]

Did a Google product search on these two movies. There must be a dozen retailers claiming to have these movies for sale in Blu-ray format.
Amazon even has a couple of used copies through their Marketplace.
But I notice they are all online mail order retailers. No brick and mortar stores. When I try to check store stock from stores that have such features (i.e. Best Buy) it shows not available in stores.
I bet it is a mistake. I personally am not up to ordering just to see what I would get; for an almost certain return to the seller. I suspect if one did try to order they would get either the standard DVD or the HD DVD. At the very least a email about the item not being available would be received. But who wants to risk receiving a HD DVD and have it counted as a sale in their favor.
