This deal has ended.
Yes, one cent. Buy.com currently has the Belkin Tunebase FM Transmitter for the iPod Nano (and only for the 1st generation plastic black and white Nano, not the new alumimum colored Nano) for $50.01. A $30 mail-in rebate cuts the price to $20.01 and, if you pay via Google Checkout, you get an additional $20 off $50 discount that drops the price further to only $0.01. Plus, shipping is free and there is no sales tax to most states. Don't expect this to last!
