The (discontinued) OLED model is currently on sale in a bundle at GAME. You can buy either the 3G version or the Wi-Fi only version for the same price. You will receive the console, a 16GB memory card and a download voucher for 10 games. The individual links for each bundle are in the first reply. This is a great chance to buy the (in my opinion, superior) OLED model before it disappears forever.
The following games are redeemable with the download voucher:
LittleBigPlanet PS Vita
Ratchet and Clank: Size Matters
The HD Adventures of Rotating Octopus Character
