Hi, i've a product that has 3 feature:
thickness , length and package.
I've created the charateristic with the value and the system create me all variant.
So the problem is that the only feature that determines different prices is the package: if it's package 1 the cost is 10 euro , if it's package 2 the cost is 20 euro.
So there is a way to do to say that in all variant with package1 the cost is 10 and if it is package2 the cost is 20 or i've to create the variant and changed it one by one??

I'm using starter edition.

Thanks

Hello,

The best solution will be to only use a characteristic for the "Package" feature, and use custom ITEM fields (business edition) and create 2 dropdown for your 2 other features.

If you only have the starter version, YES you'll have to automatically set the price for each variants, but your can actually use Mass actions to do it in "Mass".
