An AliExpress buyer was confused about UK import VAT rules. Their item cost $160, which is under the £135 duty threshold, but shipping was $240, and they were not sure if VAT would still apply. They believed VAT is calculated on the total value, including both goods and shipping, not just the product price. To check how much VAT they were being charged, they used  vatcalc.onl a free tool that made UK VAT calculations simple and provided instant results.
