Just keep it. Honestly have you heard of Wii "failures"? The only problems were during launch when the updates bricked the Wii and even then you could send it in to get it restored.
I don't know why you would buy a warranty anyway. Manufacturer warranties are always better than retail ones. Also if you got your Wii at launch and registered it the warranty is still good for 3 months and 3 days.
