I was looking for a laptop on Dell's site and found two almost exactly specified laptops with a difference of more than 300Euros. The laptops are, the expensive Inspiron 1710, and the cheaper Vostro 1700, both of which are listed on Dell's website. The only difference between them is that the Inspiron has an Ultra Sharp 17" screen while the Vostro's 17" LCD isn't Ultra Sharp branded. Also, Vostro comes with Vista Business which according to Microsoft's website costs more than Vista Home Premium shipped with the Inspiron. Click on the images for a bigger image in each case.

Also as you can see from the next screenshot even the cost of the same battery varied from 36.30 Euros to 10 Euros.

I found the Vostro laptop after browsing the askaboutmoney forums and finding this tabulated list of Dell Prices extracted from the Dell website. (Thanks to dingding). I looked up the list of all Dell prices in this easy to compare chart and then selected the Vostro from the list. This is a classic example of the benefit accessibility to information has to help you make the right decision. All the data from both sites is in the Dell website. In the Dell website you've got to go through each and every configuration to get the price details. In the PC Pricer site the information is in an easy to read table ready to help you make the better deal.
