Price Comparison Prevention

The retailer makes it hard for you to compare the price of an item with another item, so you cannot make an informed decision.

Retailers typically achieve this by creating different bundles where it is not easy work out the unit price of the items within the bundles. This was a common practice with mobile operators in the early 2000s. Some supermarkets (e.g. Sainsburys, shown below) still use a similar technique, selling packaged products without showing the price per weight. This makes it impossible to work out whether it's cheaper to buy loose items (priced per weight) or packaged item (priced per packet).

In the screenshot of below, it is not possible to compare the price of the first item to the second item.
