We joined DirecBuy a few years ago. What we have noticed is that their membership fees for new ppl has risen in the last couple of years and obviously they make a good profit as they were able to expand and move to a new building.
The prices they offer are NOT ALWAYS the lowest.
So I suggest you still do your research and shop around.
We did buy appliances from them, they are cheap in that area, fridges and stoves.
