If you run a production run of let's say 10000 cases, the price will certainly be very cheap. cheaper as my estimation.
But if you order in Batches, just as an example, of let's say 500 cases. The manufacturer has to mount the injection moulds run the batch, dismount the moulds again, so making smaller Batches is more expensive then running big batches.
But there is no other way for us to realise this. because your thought is quite good, BUT, we can't just go ahead and try to explain the IRS that the 250.000€ in the associations Bank account is for refining the injection moulds, at a later date, not yet determined. -Profit- ...
We also can't go ahead and calculate a price for 1000 Preorders to cover the rest of the missing money towards the injection moulds, because then we would make again -profit-
So that has nothing to do with, we're no big fans of preorders, it always comes down to the point, that this is a fan project, done by M-E-G-A e.V (registered association), with the law given condition, not to make profit and we do, all we can and have to, to obey the law.
So even if the MEGA65 would cost more in the end, compared to, what it would cost in production runs of a 10 of thousands,
we would be able to produce the MEGA as long as we need and we stay within the associations statutes and the german law.
Your example is based on a companies point of view, how they would produce a product like the MEGA65. -profit orientated-
(Which is not a bad thing, if you're a company)
We have to choose another approach as an registered association, to obey the law.
