What does sale and out-of-date model mean?

It is the first time ever, that we distinguish between sale and out-of-date model in our new shop.
A sale model can still be ordered.
It can be post-produced on demand and on fulfilment of a minimum order quantity.
An out-of-date model is already discounted.
Only the available stock quantities can be ordered.
