Best website for price comparison?

[dr.girlfriend]

We know what laptop we want to get DS, and are hoping to get a good Black Friday or Cyber Monday deal on it.  Is there any site you guys use that will send you notification of price drops that would include those special kind of deals?

Slickdeals maybe? Camelcamelcamel tracks Amazon prices.

I follow passionate penny pincher on Facebook and she posted a searchable black Friday comparison list that might be helpful. passionatepennypincher.com/black-friday-ads-prices-comparison/
