If you haven't blown all your money on games during Steam's Halloween Sale, you can grab some hardware at a discount, too. Both the Steam Controller and Steam Link are marked down, to $35 and $15, respectively.

Each one normally sells for $50, so if you want, you can buy both for the cost of one. Otherwise, the price of the Steam Controller amounts to a 30 percent discount, while the Steam Link is marked down 70 percent.
