If you create two listings with prices that include VAT, then the buyer should not be responsible for paying VAT again on the virtual bundle. The VAT should be included in the listed price and paid by the buyer at the time of purchase.
Kallis, If you create two listings on Amazon, both of which include VAT in their prices, then the buyer will not be responsible for paying VAT on the virtual bundle listing. The VAT will already be included in the price that the buyer pays for the bundle, and the seller will be responsible for remitting the VAT to the relevant tax authorities.
