I thought that was the default behavior. I think in terms of engineering, it sort of makes sense. Since a product can have multiple sellers. I am sure they could change it. My gripe was making a list for example, and wanting to see the total before adding to cart. It is PITA nevertheless. I am sure there is some psychology behing it like once you put it in cart, they give you a "cheaper" price you have nothing to compare it against. I've logged in with different accounts before and saw different prices. These days I try to buy local as much as I can.
