Local Markets: Santisok Market & Yong Dee Market
It is a popular place for the locals to shop. Don't expect it to be big like those in Bangkok. It is enough to serve the local shoppers and Malaysian and Singaporean tourists.
Pretty much anything from clothes (Polo, Abercrombie & Fitch, etc), sport shoes, electrical appliances, DVD/ CDs (of course pirated version with nice packaging), etc. However, don't expect to find many handicrafts or local souvenirs here.
