Because there are a few bad apples who try to abuse the Returns process, if we are not at fault, there is a 25% restocking fee, and the buyer must pay to return item. Otherwise, we are more than happy to accept responsibility if the ad was misleading or information was incorrect. If you are only moderately certain this item MIGHT fit your application, there is certain risk involved for you. Buyers who do not accept responsibility for their risk and try to hold us responsible for their inability to do their homework in advance are also subject to being banned from this store in the future. I'm sorry, but we are not WalMart. Make sure you read the ad, view all photos of the item, see all Checkout Messages in detail! Contact us in advance if you need more info about this item. If you do not agree with this very simple (and very fair) policy, please pass us by.
