If you use a Mac or an Android, e-commerce sites may be charging you more
The Washington Post - 11/03/2014
People have a mental model of shopping that is based on experiences from brick-and-mortar stores. We intuitively understand how this process works: All available products are displayed around the store and the prices are clearly marked. Many stores offer deals via coupons, membership cards or to special classes of people such as students or AARP members. Typically, everyone is aware of these discounts and has an equal opportunity to use them.
Many people assume this same model of shopping applies just as well to e-commerce Web sites. However, as we are discovering, this is not the case.
