I was doing a renovation in my laundry room and had an odd attachment that I needed. The Otter Co-op almost always has the piece I need. They are close by, covenient and there is always someone available to help. I didn't need to walk for miles through the store checking every bin and wait forever to find someone to help me. If I added up the time and gas, the Otter Co-op is still far more economical.
