This deal has ended.
Update: the price has gone up to $33. Amazon has the Motorola H500 Bluetooth Headset in Nickel for $19.99, after a $5 mail-in rebate valid through 1/31 reduces the $24.99 price. This is the best deal I've seen on the H500. Shipping is free if you spend $25. There is no sales tax (except KS, ND, WA). Of note: the Motorola HS815 Bluetooth Headset is also $19.99 after a rebate.
