First, let me point out: I've found other people asking about recalculation of orders after e.g. removing a product, and I know about issue 10735 which should address it.
However, this issue only has 9 votes so it'doesn't look like it's going to be tackled soon :o)
I'd like to do tackle this issue myself, but it looks not that easy. So before diving into that, I'd like to ask
How do *you* (everyone here) deal with changes to orders?
This is not uncommon, is it? E.g. a product appears to be unavailable so has to be removed from an order, a quantity needs to be changed,....
Currently, it's so much (error prone) manual calculation that I can't imagine people doing this.
So, I wonder how other shop owners are dealing with this??
