What's the best way to get a Nintendo Wii at the retail price?

The Nintendo Wii is still ridiculously hard to find in retail stores. So what’s the best strategy for getting one without paying the inflated going rates on eBay or craigslist? Is it easier to find at brick-and-mortar or online stores? Which stores are the best?

I know that Apple has a site that shows iPhone availablitiy at their retail stores, which was helpful when the product was difficult to find. Is there any equivalent site for Wii availability?
