300€ is still a lot of money.
That equates to around $431 AUD, which is the asking price for the pro bundle in retail stores here.
I just want a basic bundle for around $200-$230 because I’m a cheap-ass and will only use the Wii U as a secondary console.
You can get a pre-owned basic from EBgames for about $240.
