This is a STAPLES IN-STORE ONLY DEAL.
Staples has a $100 off coupon (multiple use) on any Windows 8 laptop (with some minor exclusions) that they released today via print ads and email. This coupon says it is valid only on 11/21/2012 but it actually works TODAY and will work tomorrow as well. I know this because I just bought the laptop for $250 not an hour ago from my local Staples (Renton, WA) using the printout of the attachment.
A scan of the $100 off coupon is attached here (courtesy of a member from a competing and overweight deal site):
Right now, there is also a $100 off discount on the same laptop in-store. Combined with the coupon, that makes it $200 off the original price of $449!
+ $450 Samsung Series 3 NP355E5C-A01US 15.6" Laptop
- $100 Staples In-Store Instant Discount
- $100 Staples In-Store Coupon (see attachment)
$250 plus applicable tax
In my opinion, this is better than the Newegg Asus X501A or the Best Buy X401A laptop deals, both of which are for the same price ($250), since the Samsung laptop comes with an optical drive.
EDIT: The ASUS X501 deal has only 2GB RAM and 320GB HD and NO optical drive vs. 4GB RAM, 500GB HD, optical drive for the Samsung. So in my opinion, that more than makes up for the underperformance of the AMD CPU compared to the B820 Celeron in the Asus. Make your buying decision accordingly).
