Six Months of SiriusXM Service | $30 | Plus $50 Amazon gift card | New accounts only

Update: Offer is no longer available.

For a limited time, SiriusXM is offering six months of their online streaming service for just $30, and they’ll throw in a $50 Amazon gift card on top to sweeten the deal. The catch is that to cancel the membership, you’ll have to call the company at 1-866-635-2349, so it could be a bit of a pain. But hey, it’s basically $20 of free money.

Note: New SiriusXM accounts only.
