Perhaps you’ve been eyeing the new slimmed-down Sony PlayStation 3 120 GB, but how do you justify throwing 3 bills down on a system that so closely resembles one you already own? By getting it for 1/3 off, that’s how. If you sign up for a Sony Visa Card, you’ll get a cool $100 credit after a first purchase of $299 or more at SonyStyle.com. The credit shows up on your account within 12 weeks of the requisite purchase. Then you can pull off a $199.99 price on your PS3 120 and even enjoy free shipping. Of course, you don’t have to spend it on the PS3, so browse around the site for the product of your choice. [via dealnews]
