All pricing for products and services should be transparent at first sight (Complete total of all taxes, fees, charges, etc)
Airlines & Hospitality are horrible about advertising one price then adding charges/fees before checkout making the advertising deceptive. There should be one price.
The Health & Wellness World don’t post any prices. It should be transparent what they are charging me before the service is given. That same price should be the price charged to my insurance (not more).
At the grocery store and online shopping. The price should include all said charges the moment you see the first initial price. In store, the tag should already include sales tax and any other fee that may be applied. Online, apply zip code before shopping and it should adjust the price accordingly for shipping, sales tax, fees, etc.
The consumer should not have to start a research project to determine the best deal on a purchase.
