I am looking to replace my aging MX 1000 and really like having the extra side button for using Expo. The Performance is an 8 button mouse and if the two extra side buttons register it would be fantastic to get to set those to do Expo and Scale.
I went to Best Buy... picked up the mouse... it rang up at $99.99... went to one of the sales people and showed them that the price on the web site was $84.99 and was told that was an on-line only price... I showed him that I could elect to pick it up at the store... and he still said that was an on-line only price.
Gah! I refuse to pay $99.99 when I could have bought it on-line from the same place for $15.00 less.
Never going to buy something at Best Buy. I will wait to buy the mouse at another store when they put it on sale.
