European states have different VAT rates too. A company advertises 999€ and then depending on the state it can be either 832,5€ + 166,5€ VAT or 839,5€ + 159,5€ VAT or 799,2€ + 199,8€ VAT etc.
In the case of Apple they sometimes do this and other times not. So for example the iPhone 14 is 999€ in both Germany and Austria, even though they have 19% vs 20% VAT rates. However in Finland which has a 24% rate the iPhone 14 is 1039€.
