Buy.com has a Wii Sports Accessory Pack for $21.99 that you can add-on to the Nintendo Wii's Wii-mote to make their sports games more lifelike. It includes a golf club, tennis racket and baseball bat. Shipping adds $6.28 and there is no tax (except CA, MA, MD, TN). This is the lowest price I could find (the pack normally sells for $39.99).
