Now i know that one theory is that Amazon is an expert on on converting browsers to buyers s the objective is to get the peep to Amazon as quickly as possible therefore having them click to Amazon to find out the price is useful.
The other side of the coin is to try to pre sell the peep before they click to Amazon in which case having an updated price would be useful.
My opinion is that sometimes Amazon (or the person selling the item on Amazon) has done a good job of explaining the product on some items and a really lousy job on others.
Therefore my response would have to be it depends on the item.
What is your opinion?
