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, an 8GB memory card and a download voucher for 6 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:
LEGO Harry Potter: Years 5-7
LEGO Batman 2: DC Superheroes
LEGO Indiana Jones: The Original Adventures
LEGO Batman: The Videogame
LEGO Pirates of the Caribbean: The Video Game
LEGO Star Wars III: The Clone Wars
