With this do you think that advertised discounts are always the best deal? why or why not? what is a real-world scenario in which the discount is not the best price?

Sellers can put any value they want on an item and then offer a discount. It may or may not be better than a price that is not discounted at another place. Always remember to check if you're getting tricked into a deal or if there's a better price somewhere else. For example let's say you're buying 2 pairs of jeans from walmart online for $30.However, target sells the same pair of jeans for only $10. If you bought two pairs from target you could get a better deal because you'd get the same product for 10 dollars less than target.

Have a great day/night! <3 <3
