Many television infomercial advertise a product at a very low price. after you order the product, you find there is a fairly substantial shipping and handling charger.

This is an example of multiple pricing.

Explanation:

Sometimes if you add all the extra charges, like shipping and handling, you might realize that the product being offered by the infomercial is actually more expensive than similar products that you can buy on retail stores or websites.

Infomercials do this on purpose, they use low selling prices as bait, but then they charge very high fees for processing your order and shipping it.
