Chiang Mai is a great place to shop. Sprawling markets during the day and night carry items from cheap trinkets to skilfully made local craft. ATM's can be found all around, but all charge 150 baht to foreign cards, except for Aeon. The most conveniently located Aeon ATMs can be found at Central Airport Plaza Chiang Mai southwest of Old Town on the 3rd floor, and at Tesco Lotus north of Old Town at the superhighway at the corner with Atsadathon Rd, ground floor.
