What was originally sold exclusively through Nintendo.com, Best Buy is now selling the Nintendo DS USB connector
in stores for $39.99. No word on how long the promotion will last or its availability, so run on down to your local
Best Buy if you're in need of a wifi fix without the online shipping.
Considering Nintendo.com shipping
costs of $5.00 bring the USB Connector to $43.03, it may cost a few
bucks more to pick it up at your local Best Buy instead of grabbing it
at Nintendo.com, depending on the sales tax rate in your area.
