excellent customer service!

Keep on keepin' on! Living in Nova Scotia puts me in somewhat of an aviation backwater where getting aviation hardware can be a bit of a nightmare. Military Fasteners resolves most of the angst and dealing with the friendly and helpful staff I find there resolves the rest.
