My dad is the same with gas price. If gas is 156.9 cents a litre? Nah to him it’s 156 cents a litre

Then leave the advertisement alone. They still print the prices on tags at each store location.

Let them send out flyers saying item A is $20 *plus local taxes but when you get to the store the pricetag on the shelf should say $23.50 or whatever the markup ends up being at that location.

Even if it were an exact clone I don’t think a single company should have a monopoly on the idea for almost 30 years. Pokemon red was released in 1996, 28 years ago. Why should they still be able to be the only company that releases pokemon-type games?
