Wevat app looks like this:
After entering, register first, and there will be an interface asking you the time of entering and leaving the EU, that is, the itinerary. You'd better fill it in lest you forget it. However, you can skip this step and start the tax refund directly. The main panel is as follows:
After buying something, you can scan the receipt directly with the camera, and the app will verify it in the background. After verification, a detail will come out, and you can see all kinds of things you bought in various stores and the corresponding tax refund amount, which is very convenient.
Then generate a tax refund form and print it out. When you leave England, take this to the customs and stamp it. Remember to take everything you buy to the customs. There may be a spot check (you can take the fast track without queuing). After stamping, the list will be taken away, and your tax refund will be on the way. Generally speaking, the tax refund will be received within one week, and the faster person can get it as soon as he gets off the plane.
Britain's current tax rebate is almost such a step. However, please note that some things are tax-free, so you can't return them, such as catering, children's clothes and tickets.
