Audio deals you bought that seem impossible for the price?

QSA fuse...Tekton Moab...Raven Blackhawk...

Unless it’s an discontinued/closeup, b stock item or overproduction/overstock, I don’t believe any well established audio manufacturer will build product and sell it below cost!
Impossible!

Klipsch CF-2 speakers for $75.

Recently I tried to purchase some footers for my speakers and they said they would send them free of charge.  I just received the shipping notification today.  No lie, free pie, I'm not sure why, but you know the old saying about the gift horse...

When I was selling home audio at Magnolia H-Fi in Seattle, WA, USA (mid-80s), the manufacturers were often ordering a great deal for employees. 
A few come to mind:
1: ADS was just releasing their CD3, which had excellent DACs, filtering, and build quality. I jumped at the chance (for the silly price), and it’s still working and usable today. 
2: Tandberg offered 30 cents in the dollar deals and free shipping and no tax. I scooped up a pair of monobloc class A power amps and the matching preamp. Stunning. 
3: Kef Reference 103.3 speakers via the same deal. Still sound stunning, excellent coupled-cavity bass, downward firing, excellent mids and highs, on stands with a slight backward tilt to put  sound at idle sitting position. 
Too many more to waste your time.

1. No one said they did.  

But  

2. This happens all the time. Think about it.
