I was talking about the sale price of the product. However, yours is a good point and it should be taken into account for the cost price of the kit which in some cases should be set to zero. At the same time, there are some use cases in which a kit can be used to include another product automatically, while the "kit product" has a meaning as a product too. -- Albert Cervera i Areny http://www.NaN-tic.com Tel: +34 93 553 18 03 http://twitter.com/albertnan http://www.nan-tic.com/blog -- tryton-dev@googlegroups.com mailing list
