The shops and small convenience stores in Phitsanulok sell groceries and daily needs at a much lesser price than bigger malls, this shop near the Naresuan university is a great deal better. This store sells everything from eggs to alcohol. The guy in shorts is the store assistant and the guy at the counter is the owner. They sell little snack packets for 5 bahts a great deal cheaper than Tong garden.
