Nintendo and Amazon have not always been such good friends. For some time, Amazon did not even sell the Wii U or 3DS direct. Now it's a different story. Amazon offers the Wii U and 3DS directly and now is offering select download codes which can be redeemed on the Nintendo Eshop. If you're a Amazon credit card holder, you can receive 3% back on your purchases. This doesn't completely replace the Wii U's Deluxe Digital Promotion but is a nice perk.
