It might be a price error, but also it is not the same model.
Office Depot has the same model as the one in Staples, you have to look really good in the Office Depot web site.
Office Depot: Presario 2800T-1.6Ghz Prices Starting at $1924
Staples: Presario 2800T-1.6Ghz Prices Starting at $1785 +$75 shipping.
Office Depot resario 2800-1.6Ghz Price at $650 Out of Stock
Not the same model.
Not A Hot Deal, Since is Not the Same Model. It would be a hot deal, if it wasn't out of stock, to buy right out of Office Depot.
