I have these, they work great, they work with Vista.
AND, for the first time I can see that if I purchase more than one, I would save money over their previously listed sale price.
Of course, this assumes I buy more than one and the delineation of the shipping charge doesn't kill the deal for me psychologically, from the get - go. But, $17 and change beats $30 all to heck with three sets in the cart.
Additionally, I will say that had these been offered at $9.99 for a pair with free shipping and the second or third sets (pairs) offered at $3.99 each, I would have bought three sets the first time without thinking twice. And, the "cost" to me (and to Fling) would have been the same . . . just a great example of how it works (worked) in my head (the free shipping) . . . and I would bet I am not alone. I am starting to "get" the whole shipping thing I suppose, but it would have been GENIUS from a marketing "angle" to do it the other way (as in the immediately aforementioned).
BTW, and yeah, it is picky, but it is switches, not switchs.
