It's even hard finding them online and the official e-shop or whatever remains overpriced.
Cash Crusaders are basically gamble, your lucky to find any games there, but of you do it's a score. The racks are filled up with just about every Xbo360 and PS3 game though. Wii games are so rare (the few good ones) that they fly out of the store.
The Wii U games price don't want to come down anymore either on takealot and kalahari, there was like one awesome sale that lasted a week or two and that was the last of it.
