If you live in NOR (North of River), there is a good option for you. I also knew it recently.
There is a huge grocery market (farmer jack) in Geerawheen, just next to Geerawheen Senior High. I have been there 3 times already, and feel that the price is much lower than other places.
It is open 7 days.
One Good thing is: there is NO special Smells of pork, as they only use "Female Pigs" if you buy from the meat stall inside the market.
Hersman Supermarket.
It closes around 1900-2000PM for every day. It provides good quality of foods but the price is not cheap. It also expends its business to the city.
Not always go there even drive pass it every day. It is very popular for local people.
