Seen numerous people on NeoGAF order from them without issue (they had some big promo back around Black Friday that people were using to get awesome deals on video games). They seem pretty reliable. I personally have not used them though.
A store like 45 minutes away has one. If I were to order, would Walmart hold it until the weekend?
Well, to answer my own question, in case others are wondering the same thing, Walmart will indeed hold it. Going to pick mine up this weekend.
Added to my cart, went to check out and when I went to put in my billing info it said they sold out. Glad they don't hold the item for a certain amount of time while it's in your cart and you're checking out. It's now only available for in-store pickup.
I've got the beige ones, and while I like the look of them more than the black, they definitely aren't worth the extra $65. The black ones on sale also have the short cable which is a really nice touch.
