PCWonders.com lists this item in stock, at a price of $24.89; considering the fact that on Pricewonders.com & shopper.com, the only ones who list having it in stock are the ones that have a price not too far off from what MSRP is, I don't know if it really is in stock or not there.
IF you really want to order this mouse from them, I would check by calling PCWonders FIRST, and if they do indeed have it in stock, the shipping is relatively reasonable from them.
IF, however, you're willing to order through Amazon.com or Buy.com and don't mind waiting for the mouse, then I would say go for the Buy.com one, because it's only a few cents more, and if you order before the free shipping ends, it makes it a better deal than the Amazon.com one. Otherwise, get the one from Amazon.
