Most of the time, we get what we pay for. When marketers want to increase their margin, they either increase the price or decrease the quantity. In this picture of paracetamol tablets, the supplier has clearly done the latter. When I opened the box, I thought the foil was a bit short. They reduced the number of tablets from 24 to 20 and kept the same size box and price.
Banks play the same tricks. If a deal is too good to be true, it probably is. If they don't want your business, they will raise their price (interest rate and fees) unashamedly, often citing risk as the reason. If they are keen for your business, they might offer a discount.
