Why Do Prices Change When You Shop Online?

Imagine you're trying to buy a toy, and the store says it costs $10. But when you come back tomorrow, they say it's now $12, and maybe even more! This happens because stores want to make sure people pay as much as possible. They might do this by watching how many people look at the toy or try to buy it, and then change the price like a game of hide-and-seek.
