Hi,
the case is that my client is selling catering diets. Wen need to calculate priace of variants of those diets, for example vege diet has calories variants (1200, 1500, 1800, 2000 … ) variant that you can order it for whole week (7/7 days) or only week days (5/7), you can order it for 1 week, 2 weeks, 3 weeks… About 5 options there, you can also order as it is with all igredients or without 2 or 5 igredients you don’t like. And thats not everything 
All variants multiplies and it makes about 960 variants for 1 diet type (1 product) so we need to make some auto-calculations here not to put all 960 prices manually (x14 products that makes 13K variants 
)
Thank you in advance for any help here
Regards,
Łukasz
