Buy.com has the Samsung WEP470 Progressive Noise Filtering Bluetooth Headset for only $2.99 including FREE shipping after $20 mail in rebate. Basically, buy it for $22.99 and submit for the $20 rebate and only spend $2.99 for this great headset!
Be sure to click ‘Budget shipping’ to get the FREE shipping because they have it automatically have ‘Standard shipping’ checked, which is more. Also, for the 3 per household limit, they have to be one per envelope, but I don’t know if they accept copies of the receipt/invoice, so just to be sure, do 3 separate orders. And finally, the rebate is in the form of a Visa gift card which can be used at any stores that accept Visa.
