If you don't the price of something you want to buy then there's a high likelihood that you might be ripped off. Someone I know bought something for her child and then later found that an alternative to the product she'd bought [that would have served her better] cost half the money she'd spent . . . and yeah, she was really angry when she found out. Though it might not be possible to visit all stores to compare prices, you at least have the net. Look up the price of anything you want to buy. That way when you want to buy something you don't regularly buy, you won't get ripped off.
