I bought a Lenovo G50-70 Model 20357 from Staples last week. The receipt shows Lenovo G50 - 59421. Regular price is $569.90.
I used the 50% coupon so it came out to just above 300 w\tax. It was an open-box item, and has a noticeable but not too significant scuff on the plastic above the screen. I have used for a few days, and haven't noticed any problems. PM me if your interested. I plan on passing by Staples tomorrow night, and will return if not sold.
