Q: Is there any way I can find out what UK customs fees will be on my order before I place it?

A: Well, we would have said we have no idea, but we have had people in the UK deliberately order under a certain amount at a time so that the total does not hit a certain threshold that triggers customs fees.

But hey, we found this UK government page that looks really useful:

We’ve gotten the most complaints from UK customers, but other countries have duties too, so, if you’re worried about it, check around for info from your local government.
