Yes, fees and value added tax are not included in the price. It's common practice to include that here in Sweden, but not required. The reason for this approach is to keep our prices simple and accurate for everyone as taxes varies between different countries.
FriendlyPerson Because if so doesn't that violate some payment processors/networks terms of having not to charge these fees,
I have to look that up for Paypal, but for cryptocurrency payments there are no such requirements as the sender pays the fee anyway.
We used to allow custom payment amounts via Paypal and during certain periods of time we could receive multiple payments with amounts less than $0.5, with Paypal's transaction fees starting at $0.3/payment that simply wasn't viable and the fee was passed down to the end user as a temporary fix to "discourage" the expensive micro transactions.
