The bundle comes with separate codes for Sly Cooper Thieves In Time and The Lego Movie game(Vita versions ONLY, even though Sly is cross buy usually).
BOTH of these codes expire TONIGHT(3/31/16). So use them before they expire.
Moreover, Walmart considers these hardware so the return period is ONLY 15 days with these.
So if you're going to buy one and then debate if you wanna keep it or not don't wait too long.
To those of you with expired codes, I just live chatted with Sony and explained the situation. The rep escalated me and asked me to send him a purchase receipt and scans of the expired vouchers. Can't confirm yet that I've received new codes, but looks like that might be happening.
