If it's too good to be believed...it's not.
The Isle of Mann is known for the moto race event that the normally sane lose it during the event. This thread seems to indicate that some locals think that the madness is transferable.... ;) 😏
Audiohifistore.com is a SCAM
I personally know an individual who was scammed by this website and lost money. The website looks legitimate with actual photos of equipment, but the equipment was never delivered. The manufacturer of the equipment was able to verify the serial number of the equipment, so it looked legit, but this is a very slick scam. Beware!
Moral of the story: use a trusted seller.
