Great tips! These types of scams are common in tourist areas. I know in West Yellowstone, Montana, just outside of Yellowstone National Park, you can simply ask for the 'local discount' to knock a big chunk off the price of pretty much anything you decide to buy.

Price gouging also happens in Mexico and the Caribbean. The best way to beat it there is to learn some Spanish and be willing to walk away from the deal. Most locals will quickly change their tune when you start to walk out of their store.

Thanks for the tips!
