Prices in Lhasa are generally high. If you want to buy special products, here are some relatively cheap places:

* Tibetan restaurants: Tibetan restaurants are a good place to buy Tibetan specialties, with relatively low prices and authentic Tibetan food.

* Local market: There are also many stalls selling specialty products in the local market in Lhasa. You can visit the local market and compare the price and quality.

I hope the above suggestions can help you, and wish you a happy shopping!
