"Grocery Stores" in Thailand

This is the local "grocery store" in Uthai Thani. Hy-Vee, Von's, Stater Brothers, and Safeway do not exist in most Thailand cities. However, the cities that are extremely large do have "TESCO/LOTUS" and "Big C" (two British chains). We have a "7-11" store but no stores that sell canned food, packaged food, frozen food, or refrigerated food. The market opens around 5 am in order for people to get meats and other perishables before they spoil during the day when it heats up to 95-100 degrees. Everyone at the market greets us with smiles and cheap prices. A meal for two will usually cost about $1.50. We will soon be leaving for our permanent site which is so small it doesn't have a "7-11", so we will have to travel to the "big city" (about 40 miles from our assigned village) and stock up every few weeks. There will be several small "restaurants" which are usually open air stands with tables outside. Looking forward to it!!!!
