Normally $199.99, you can purchase a 3G and WiFi PS Vita for just $139.99. The one caveat is that it requires a rebate to be mailed in. The Vita is already discounted $20 automatically, but with the mail-in rebate you can save an additional $40 which brings the Vita down to a much more attractive $139.99.
So if you don't mind going through the hoops of snail mail, head on over to TigerDirect and take advantage of this deal. It's only valid through December 14.
