There are about six 7-11 stores. No Starbucks, McDonalds or Burger King, and we like it that way.
We have one big department store with a fix-it section to get all the bits and bobs to make any backpacking repairs you might need. Most of the local artisans still operate in the same tiny stalls they've had for years: they carve, braid, string, and twist up jewelry during the day and sell it at night. There are clothing stores selling everything from cheap t-shirts to the latest fashions. CDs and DVDs can be found in most trafficked areas. Sunglasses can be bought on every street corner. All sorts of diving equipment can be found at competitive prices. You can buy any size backpack or bag you might need for your trip in one of the many bag shops. There is a custom wetsuit shop who can make you a diving wetsuit designed like your favorite superhero.
