I bought it for the PS3 when it was on sale for $9.99, they did a decent job of cleaning it up. I refuse to buy anything from the WiiU store, Nintendo seems to always screw up anything online, while the WiiU is better its still horrible.
Nice - good price point there - I'm happy with the eShop experience - it is easy to find what I need, download/installs are quick and easy - I can turn the system off and things continue to download, I can reinstall games if I delete them from my Wii U. They run some nice sales and VC bundles and well the 10 percent back is rather awesome.
It is quite awesome having a Wii U loaded with games that I can play without getting the disc. I still enjoy collecting the discs for the big retail releases, but still buy quite a bit from the eShop.
