Well, this is a place where many visitors go so there is a lot of shops there and even if it look splendid becareful before using your credit card because you will overpay almost all the things there.
But I admit that they really have lots of beautiful stuff there.
Unique Suggestions: Spend the first day comparing all the prices, and go back to the store where it was cheaper. Sometimes prices are doubled from a place to another. Even if you overpay, it is better to pay two times more than four times...
Fun Alternatives: Go to the tourism office and ask for leaflets about manufacturers or factories if you plan to buy some local poteries. There is still some of them in the area so you'll just pay factory price.
