Bargaining in the markets! Know how much you're willing to pay. Start off at a very low price. They'll look at you like you're crazy, but keep your stance. You can always try their neighbor, they'll relent or give you a very reasonable price.

Try to be practical in every setting, but when you're in a foreign land, be extra nice to people but don't look like total easy prey (esp. when shopping!). You've got to be a shrewd bargainer and be wise like a snake so you're not easily taken!

Baggage cheat! Airlines say 2 carry-ons only, but I've always gotten away with my standard carry-on, a large purse and a backpack! As long as you can stow it away safely under the seat and you can carry it all! It may help if you're a girl too! =)
