If you are in the UK do not set up an order or continue your subscription above £135! I just got asked to pay a £50 import fee by UPS when my regular subscription was being delivered because my order was above this. I obviously returned the package and am now making my subscription smaller but more regular.
I think this should perhaps be warned somewhere prominently when ordering - I don’t think anyone would pay an import fee that large without warning! After all simply keeping the purchases below this amount can (apparently) save a nasty surprise.
