I'm surprised that Costco isn't carrying it yet, but I sure they will by this fall.
My local Target has already been clearencing Vita accessories like the USB cable and AC adaptor...
I didn't see a single console, handheld, video games, or accessories at the Costcos I've been to...they seem to have disappeared after January or so...or if I did see anything related to video games at Costco it was just a wimpy selection.
all are in stock with vita consoles, games, and accessories in Las Vegas, NV, USA. and the closest walmart by me was sold out of consoles for a few days two weeks ago
The Vita is still in the early stages of post marketing. Just like the PSP, it will gain a steady ground for consumers to pick up on it in a few years. Provided that hackers/piraters don't destroy it as they did with the PSP.
I was at Sam's Club the other day and they didn't have a single Vita system, game or accessory. They didn't have anything PSP related either, though they use to (don't ask when, as I don't remember, I don't make it to Sam's Club very often). They did have plenty of stuff for PS3, Xbox, Wii, DS and 3DS.
Never heard of that store... lol but every gaming store here in Austin Texas or store that stocks games, has Vita's and games...
Tesco is a UK store that started off as a grocery store and now is more like a Walmart or Target, if the store has enough floor space, or is designed to do so, they set aside floor space for clothes, housewares, electronics, garden accessories, etc.
So this post would have been more relevant in the EU forums as we seem to have no lack of availabilty in the US stores.
