Anything that ends up in ParcelfArce's hands will bite your wallet, there is plenty of literature about it on the internet. These guys are worse than Saddam Hussein, Ebola, and your mother in law together. Unless your package comes with a private delivery company (UPS, DHL, etc), it will be handled by either Royal Mail or ParcelfArce once it hits UK soil. The first one is quite reliable and won't usually get you any extra fees, with the other you never know. It's always a good idea to research which delivery options end up on Royal Mail and which ones end up in Parcelfarce's hands, just to be safe and avoid stupid delays and extra fees.
