Hi, first sorry for my Bad english.

I need help to change the price and tax information.

After the price I need a little star like this one *...and I need to delete the tax info in german " inkl. 0% ust.". My only option is to this in direkt in the list or price HTML But I don't know exactly where.

Can you specify your requirements in detail? And I can't access the image you have shared.
