This deal has ended.
Buy.com has the Logitech MX 3200 Cordless Laser Desktop for only $44.95 after a $20 mail-in rebate valid through 6/24. Plus, shipping is free and there is no sales tax (except CA, MA, MD, TN). This is the best deal around (this is $70-$100 at most stores). New Buy.com customers can use this $5 off $50 coupon and new Google Checkout users can get a $10 off discount for signing up (you can't get both).
