If you want cheap stuff to give as souvenirs, go inside the straw market and remember to barter. A simple magnet some will ask for 10 or 15 but I let them know I'm not willing to pay more than 5 and get it at that price.
If you're wanting something truly unique, go to the ally where you can watch people carving. The work they do is beautiful and worth the price, you can find people also painting over there.
