It's not though is it. It was obvious a while back what the game was, and it has finally been elucidated above ie that whilst people wait and hope for this bargain to come off, business isn't being put Tullett's (or anyone else's) way. How long is too long to wait? Is anyone going to risk dropping of the list, and potentially missing out on a bargain?
Either the items won't manifoldfest themselves, or Thorney will find someone to manufacture them for less than £200 (don't forget, you don't have a spec for it; it could be utter rubbish) - I have no idea what the production cost of a manifold is. No sensible business man worth his salt would even propose to take a financial hit that substantial, without knowing exactly what they were doing.
I think anyone with any sense who wanted a manifold will have bought one from Chris already.
The production cost of a manifold like that is expensive, it can't be automated and making a whole batch of them takes barely any less time per unit than doing one of them. Hence why it cost £750+VAT to produce them first time around.
