Hey!
Thank you very much for this little but VERY useful hack!
For Switzerland, we only need to apply 7.6% VAT if delivered in CHE and remove VAT if delivered outside CHE. So simple

Just a "little" problem: your hack give us the ability to display prices with VAT if customer not logged in BUT the child products aren't displayed the same way (with VAT) if we didn't entered the price and VAT% in EACH child product.
The price is displayed without tax.
All the infos are supposed to be the same as the parent product.
Is there a way to display child products price with VAT the same way?
Without having to enter infos for each?
Thank you very much!
