Farm Fresh Mart is tucked inside the same plaza as Gourmet Malaysia, beside what was Woodie Wood Chuck's. This place advertises quite frequently on Chinese TV, and the deals inside the store show as you can find a lot of sweet deals in there.
Remember back before T&T was a thing? This was how a typical Chinese grocery store looked like: Filthy, dirty, had that fish/meat smell...but you come because you know the food here is a lot cheaper than your typical No Frills or Food Basics. In fact, I find the produce section here to be better than T&T! If you're looking for at least one thing that you should purchase here regardless of price...it's produce.
Service is typical Asian quality, so don't expect much. There was another customer who tried a shouting match with one of the cashiers for lack of conversation, but it was all for naught as she wasn't used to the (lack of) service that's expected of an Asian supermarket.
