On top of these, the courier who delivers it in the UK will ask for a nice chunky fee also just for collecting the money.
Duty is waived if the value comes to less than £7, but it would be higher in this case.
VAT limit of £18 is on the value before shipping, but if VAT is added, it's added to the value *including* shipping (as VAT is on both goods *and* services). Again, the value here is way over so VAT is due anyway.
You might get away with nothing to pay however as not every parcel is inspected, but it's unlikely if it comes via a courier and not just standard Royal Mail. Also, some couriers have been known to hand you the parcel with no charge but send you a bill in the post later.
Alternatively, you can bring one back on a flight from outside the EU with nothing to pay if the value of all your items you bought overseas is less than £390.
