How silly....The code stopped working over the weekend as I was going to get my Onkyo 609 amp from them.
Ended up getting from Amazon Germany and saved myself another £30 over the Superfi extra 10%.
It may be true, but dealers buy them at different prices based on the quantity they order.I just got a local dealer to match that - they told me that's about what they buy them in at....I wonder how true that is?
