Hello,

I want to know if I can indicate the price of a modifier upon sale same as we can do with items?

Hello,

No, it is not possible to leave the price field empty for a modifier so the price for it can be indicated upon sale.

When you go to create a modifier in your Back-office->Items-> Add modifier you can see that the price of the modifier is set 0. You can change it or if you do not change anything in the Price field the price of the modifier will be automatically zero, even if you leave the price field empty and Save the modifier. 

                                                           

Hi, is very important to add (like products) options to choose modifier price.

Thanks a lot
