We have all experienced it at one time or another and there is no way to avoid it 100% of the time. I have gotten "taxed" pretty heavily a couple times my self and have learnt where to buy things in order to avoid it. I encourage everyone to contribute from their experiences.
My first piece of advice is... if you look gringo and are at the beach in Viña; don't buy anything from the guy that rolls up and down the board walk selling refreshments and snacks. He got me real good once... CLP $800 for a single bottle of water. I didn't really think anything of if because that is pretty much on par for here in Canada. Then I got to one of the permanent stands that post their prices... and I just realized that I just got charged close to double what the going rate is.
So my first tip is… when ever possible buy from and establishment that posts their prices. And avoid the street vendors. They will squeeze you for what ever they think they can get.
Secondly... if you are looking for property. Ask a Chilean friend/or Chilean significant other to check it out for you first, alone. Last October my wife and I were out looking at some properties in an area that her parents are fairly familiar with. We got some prices and when we got back to their place shared our information and they were both kind of shocked at how much we were beign told. The both attributed it to me and suggested the sellers were increasing their prices a fair bit because I look like a forigner.
