Find the Best Prices (including tax and shipping) with Google Product Search

Use Google Product Search to find the best prices, including tax and shipping.  For example, I searched for the Viewsonic 10 inch digital photo frame.  The results show that Office Depot has the best final price of $64.95 for a brand new unit.  I also like Buy.com and Amazon.  They used to be very competitive, but these days, many items ordered from their site are shipped by a third party vendor and shipping fees could really spike the price.  This is where Google Product Search comes in handy.
