This website called GameDealDaily has PS4 download codes for pretty cheap prices. I believe you can only purchase the codes via Paypal. They send the code instantly to your e-mail. I received mine as soon as I paid for the voucher. They also have Little Big Planet 3 on there for under $40 I believe, after CAD conversion.
