Have you ever been to a flea market? Perhaps you travel a lot and have oftentimes been to the tourist markets around the world. Do you ever feel like you are being swindled? You probably are.
I can teach you the basics of haggling: the negotiation of price. The next time that you go to a tianguis in Mexico, or when you next visit a village in China, you will be able to barter your price down to what is reasonable for you.
You don't travel? That's fine. There are still many areas of life where knowing how to haggle can be rewarding. Take Simbi, for instance; the form and amount of payment is never set in stone until the deal is agreed upon. It can also be applied to business deals and it's always used in courts of law.
Disclaimer: This will not work at commercial/retail stores (eg Wal-Mart, Target, Kroger, etc).
Training & Qualifications
I was raised by an attorney; thus, I grew up always trying to barter my way. I got pretty good at it.
I lived in Mexico for two years; the few times that I visited the touristy ancient ruins, I learned to haggle prices way, way down for various items. The rest of the time that I lived there, I constantly practiced and improved how to bargain the prices in the tianguis.
Availability & Preferences
I'm usually free on Friday afternoons, Saturdays, and Mondays.
