If you dock there is a mall at the pier. It seems to have most of the same stores there as on the Main Street.
If you anchor, you will be tendered right to the Main Shopping district. If you look to the right you will see a bunch of blue and white tents. That is sort a market area. Dozens of vendors selling local crafts, t-shirts, hats, all the souvenier stuff. It is fun to go and look. My experience was most of the people did not bargain as much as on St. Maarten. So just take a look around. There are a lot of "Name" stores, Hilfiger, Coach, etc., so it's kind of what your intentions are. There some neat little stores to go into and browse around. If you go up to Paradise Point tram there are stores up there as well.
