If you've been waiting to get on satellite radio for pricing reasons, this deal should be enough to get you in the game. Buy.com has a discounted Samsung NeXus player for $50 with a $50 rebate, which means all you're paying for is tax (there's free shipping).
And hey, some states don't even need to pay for tax. Price is good for today only, so get to buying already.
