negative price

[Bart]

it would be great if we could put negative number in an item. This is for example deposit if they return empty bottles. or is there another easy way to do it ?

You can do it. Use discounts or 'kortingen'. You can use a percentage or a fixed amount

Tanks, but with discount, you need to have sometings to discount, now is not possible to get a negative total.
