Hi Phin, I am in exactly the same situation as you currently! I ordered my saber on 9th April from Etsy and my tracking status now is 'customs clearance processing complete'. Now, all i know so far is that Saberforge have told me that they label up parcels as 'LED torch and plastic tube, valued at £35' in order to avoid excessive import tax etc... But i have also discovered that USPS by default always use Parcel Force to complete the delivery once the package reaches the UK and unfortunately for us, Parcel Force are apparently the only courier in the UK who charge a 'handling fee', payable by us
. I phoned Parcel Force today in order to find out if i need to pay any charges before they will deliver. They said i only owe £15 which i presume is the handling fee, so therefore i may have avoided tax
The next stage is paying this fee, which i am told i cant do until my saber reaches the local depot which should be tomorrow, and then i can phone up and pay over the phone. If i do this they will then deliver my saber at the earliest next Monday. I have decided however that if it does arrive at my local depot tomorrow i will just head over there myself, pay the fee and hopefully return home with my saber in time for the weekend!
If you haven't done so already, i suggest you track your parcel on Parcel Force's website, as it gives you slightly more up to date info than tracking through Etsy or USPS. Better still, just phone parcel force to find out if you owe any payment and to properly find out exactly where those lightsabers are!
I hope in some way, my very limited experience helps a little
