The Sportster 4 is going to be a popular one this holiday season, and Sirius is doing a package deal through RadioShack for those Black Friday savings.

If you purchase a Sportster 4 plus a $49.99 prepaid Sirius programming card, the Sportster 4 drops down to $39.99 (so yeah, the total cost is around $90). Not bad considering that's an instant savings of $110 off the original price.
