Cheap Wii U Games? + Amiibo Questions

Is there a site that sells cheap (but not fake) Wii U Games and Accessories?

If I scan an Amiibo on the NFC for Mariokart, does this earn points (if you win races) and do those points carry on to super smash brothers?

@mattahn123: Amazon usually has some cheap prices on Wii U games. You can also sometimes catch Toyrus, they have Buy 1 Get 1 40% off or Buy 2 Get 1 free. Accessories im not to sure, might have to just google what your looking for on those.

No points on Mario Kart, the Amiibos just unlock costumes on it.

@iandizion713: Thanks!
