(MoneyTalksNews) -- Sometimes what we buy is way overpriced compared to what we're getting in return.
The first will come as no surprise: Water - here's a product that can cost less than a cent, and be sold for more than a buck: Quite a markup. Workaround? A refillable bottle with your own water.
Drinks in restaurants can be marked up 300 to 600 percent. This soda could have cost the restaurant two cents, and cost you 2 bucks. Hard to swallow? Drink water.
Then there's greeting cards: A folded up piece of paper that couldn't cost more than a few cents, but costs you a few bucks. What's a nearly free substitute that's also more memorable? Something you make yourself.
