Nop_ProductVariantAttributeValue table

Hello

I don't really know if I should post this under development, or under general support....
Anyway:

I was wondering if it is possible to allow negative price adjustments for options in products
I have noticed that price adjustments work fine when there is a positive price adjustment ( > 0) but I was hoping that you could also work with discount options (money field < 0).

That means if somebody chooses one of these, the price goes down. At the moment this does not show in the combo box

Maybe you can guide me to where this is processed and I can adjust the code myself?

Hi,

I've made some changes to the code that seem to be working, however I recommend you do  some further testing with this... However, from what I see, it makes the adjustment all the way to checkout. The only thing I don't like is how it displays the negative adjustment, but that can be easily worked out. Example: Black [-(30.00)] looks a little funny to me... I would change the formatting like [-30.00] if it were me.

Good Luck.

Jose
