You can shop at Unicentro just like any other department store. More up market is another mall in Santa Barbara. Staff will follow you around the store, which l found strange at first. However you do get used to it and they are not looking for tips just being helpful. The security will also check your bag before you enter and put a tag on it so you can’t steal.Leather goods. Anything from clothes to suitcases and beautiful jewellery. Emeralds very cheap but make sure you go to a reputable store.
You can bargain, not in the centres but the smaller shops.
