I have to reduce the price from an product not with an fixed amount but with an percentage.
So I thought that I will create a new attribute called "special_price_percentage". This value should lower the normal price with the given percentage. This value should also affect the tier prices.
Does anyone has an idea, how I can do this?
Is it better to make a custom CatalogRule as a custom class? Because If I want to create a CatalogRule I can't set the value from my attribute.
Or should I override specific classes to change all price calculations? Does anyone knows, which classes are affected?
Thanks
