I have no idea, it's been awhile since I've visited a Radioshack. The last time I did, I had my Moment with me, and the Sales person was flipping out. He kept saying that the Moment was supposed to be a Radioshack exclusive, and they hadn't even gotten it yet. I told him I bought it at Bestbuy, and he seemed kind of mad about it. He then went and called his GM (general manager) about it. I left at this point.
Though it does stand to reason that if one Radioshack were offering at this price point, all Radioshacks (at least in that area) would be as well.
