I recently (the past month+) attempted to purchase Canare 411S from Performance Audio and their "purchase" function did not work (for me) on their website.
I sent them an email regarding such, but did not receive a reply.
I then purchased the same cable online from Markertek and had the product in hand within 7 days (ground delivery) even though they were being hammered by extremely bad weather @ the time.
Not a big purchase (just 50'), but still.
