DON'T BUY FROM PARTSOURCE - Regina SK: I bought two filters for a car as there were two options and the person at the counter said I could return them as long as I had my bill. It took quite some time to find out that the filters weren't the reason it would not start. When I tried to return them, they said there was a 90 day return policy and wouldn't take them back. You find out their return policy after you call their automated 1-800 number on the back of the bill. Losing a loyal customer and 50 years of future purchases for $40 worth of filters is pretty lousy business in my opinion, but I guess integrity is not part of their business.
