Hi adubb1918,
This is the million dollar question! I was able to get mine on eBay for near to retail. Amazon sometimes has good deals, and these are the reputable players in the online market. Save the gas and avoid the stores. Check out my buyers guide at:

I just share my experience with trying to buy at Wii at a reasonable price.
Hope this helps!
Cheers,
