My parcel has made it to the local hub, hopefully Tuesday delivery it's saying.
If it does come Tuesday it's worth noting that this would have taken 15 days from the moment ups picked up the parcel.
Not great, but an idea of what others might expect if they are worried about ukara expiry's.
I did pay the fees within an hour of getting the email, however it took me a couple of days to fill in the firearms form once requested.
