I had ordered the wrong spark plugs and didn't notice until the day I was changing them. Spoke to a very helpful customer service person who walked me through the RMA process. New plugs arrived in 2 days and the refund was applied as soon as AS received the returned product. I've been using AS for over 25 years and have always been impressed with the service.
