Can consumers actually determine whether Amazon or Walmart has lower overall prices? Explain

Consumers can determine whether Amazon or Walmart has lower overallprices by comparing a certain product from Amazon to Walmart.

As aconsumer, I go online to compare whether, for example, a phone case ischeaper on Amazon or at Walmart.

However; I realized that the product maybe cheaper by 2 or 3 dollars, however when you factor in the shipping andhandling costs as well as the time it takes for the product to arrive, Walmart’sproduct outweighs Amazon’s in price.
