Located near the bus park, Aweno market is one of the busiest spots in Kampala. Be sure to keep a close watch on your bag, or better yet don't take one.
The market is always full of people who want your business and will bargain with you if you are persistent enough to not take the first offer and tell them you don't want the "mzungu price" or the price they give a foreigner.
The market has everything you could need from clothing and shoes to crafts and live chickens. You never know what its possible to find here so if there is something you just cant find in a store around Kampala, check at the market it will probably be a lot cheaper. Although most of the things are used, many are still in great condition and you can get them for under 5000 Uganda shillings or about $2.77 US dollars.
