In addition to chain stores, there are many small convenience stores and larger general stores in the area. The gratifying thing is that the price level in these is the same as in big supermarkets, sometimes even cheaper. In local stores, you can also buy gasoline for a moped, which is "served" by pouring it from a whiskey bottle. The selection in these is often surprisingly diverse and the service is friendly.
At both ends of Beach road there are 7Eleven markets, (map link 1, map link 2) and the third one is connected to the fuel station when going towards Krami (map link 3).

The nearest large grocery store is Makro (map link) in Ban Phe (about 20 km). The selection is wide, e.g. fresh seafood, chicken and pork, etc. It should be noted that all fresh products are weighed and bagged by the staff. The macro is used by e.g. restaurants as a wholesaler, so the turnover of products is good.
In Mae Phim, there are also small stores mainly intended for Nordics, for example, Viva, which has been operating in the area for a long time (Facebook, map link). The corresponding store in Ban Phe is Petra Market (map link). Their selection also includes fresh bread and pastries, more broadly frozen, sausages, cold meats, wines, and imported alcohol.
