Honestly, I have never been able to find a good price using Froogle. What is the point if I search for "cross pen model No##" and it turns up thousands of links? (as I recently did when I wanted to buy it for a gift).
Froogle/PS is nice to find things that you can buy quickly using Google Checkout. If I don't care about price, but do care about keeping my CC safe/buying something quick, I usually use Amazon or Froogle.
