One funny thing - I had shipped a mousepad that I valued at $0 (I got it in a loot crate - it's technically worth nothing to me), but I was told it must have a value so I valued it at $1. 😂
They also apparently looked into my PC and challenged the cost of the various components. This is the one I still haven't received (because UPS doesn't show I've paid duties even though I have), and I'm worried they unpacked/repacked it and now it's damaged. :(
