I already had a little read through it from your reply to someone else What part says you pay tax every time it goes to a new business? I saw the part about it going from a country with sales/VaT to a country that has the other and both of them being cumulative but can't see anything about VaT being cumulative. Could you paste a sentence to Ctrl + F? Even still £25 and £40 is like a 80% + increase in price. That still doesn't seem to add up unless it's bounced around 4 times... and it's a digital product not a physical good, why's it bouncing around so much then? I don't quite get this stuff so perhaps you could help me to understand?
