Shipping costs to UK

Hi there,
I ordered the new Umbrel Home in February and it was received 27 Feb.
The cost on the Umbrel website was £319 including shipping.
Today 17 Mar, I’ve received a FedEx invoice requesting Duty & Taxes of £49.05 !!
Looking at the FedEx paperwork the value of the Umbrel Home was 239 US dollars (about £191).
The math doesn’t add up.
Did I overpay?
Surely Duty & Tax is part of the shipping costs.
Can anyone make sense of these numwers please?
Thanks
Stan

That’s why i always prefer the local company which can ship the goods within the City. There are multiple reasons, you get the courier tracking of your product, even you can get your goods on the same day of your order, they provide the affordable service, even more concession when it comes to shipping in bulk.
