They are a front end for Worldpac. They ship from whatever warehouse is closest to you (if it has stock). I have had pretty good luck, but probably because I have a warehouse close by and they ship promptly. However, one time parts came from across the country. Luckily I only had to call their customer service once, I think it was in India... They did sub parts on me one time but it was OK with me in that case. I just bought some BMW filters from them last week and had no trouble. FWIW.
