Yeah, that's possible but I as a lawyer never recommend it. They can also open the package themselves and check its price, which means you'll have to pay even more if you bought the item at a sale or used.
They can still be suspicious and request a bank statement and this means you can be charged for customs fraud, which I'm not exactly sure how much is in UK but the general range is within 100 to 200% of the actual price of the package.
Ah, I see. I, myself, would prefer to play by the rules, but sometimes, things can be rather unreasonable..
Customs fraud sounds pretty full on, but I'm pretty sure that shouldnt happen with something like a pair of earphones, as this stuff occurs on a daily basis, if not hourly. I don't know..but I doubt it'll get that much out of hand.
Thanks for the advice and support all!
