(Update 8/1/10: As of today, price is back up to $68)
Better hurry, offer is good until Saturday at your local Best Buy store (it is now back-ordered for online, in-store pickup is your best bet). I found out about this last night, verified it just now. Logitech MX1100 Cordless Laser for $34.99 in store pickup.
MX1100 Cordless Laser Mouse has a retail price of $79, otherwise around $59 online is considered a high end performance mouse, this sale is for brand new units so it ain't one of them Logitech Dented Box deals. It's got adjustable DPI settings up to 1600dpi and 10 programmable buttons with a battery life well over 6 months. I use one for work (I paid out of my own pocket just because I love it so much). This is a great mouse for gadget fans as well as bloggers. If you are still using a corded laser mouse, run to your local Best Buy now!
