Just a word of advice...If you are going to buy these, follow the link above. If you just do a simple search on amazon, a different model comes up--where the discount doesn't apply. When I followed the link above, I was surprised that this thing only had 9 reviews at the time. There is another model with almost 2000 reviews. The deal is only for the "BLACK" model. The only difference I can see is that the black model is well, black on the side, and the one with 2K reviews is silver on the side. See for yourself, BTH220 vs. BTH220-BLACK.
