Your too late. Many firms are restricting sale of bare hard drive to 1 per person and some sizes are out of stock, the manufacturers are using any stock to supply system manufactures. Prices of drives have gone up by 30% (if you can get the one you want). This is bound to affect system prices although with all the 'special' offers about it is hard to do a comparison.
