I done another order, after the fun of the first one. It wasn't as painful this time around, here's the timeline:
9th Apr - Order placed
12th Apr - Shipped
16th Apr - Arrived in UK
28th Apr - Voicemail left to me from UPS
29th Apr - Received RIF import doc (went in my spam so didn't return until 4th May)
4th May - Fee's invoice received & paid
11th May - Package received, no Border Force tape, so wasn't opened up/inspected (contained a RIF)
So around 4 weeks, which is better than the 10wks odd when they first started back up.
