Even better, no further expense required by the lucky winner!
That's why I CAN'T sensibly enter the competition.
The import duties and VAT (20% rate), into the UK, and maybe other charges, would be something like (assuming item is CORRECTLY declared on custom forms) of $5000, or £3650).
If I entered the competition, and won. Dave sends it to me. I refuse to pay the £3650. It gets sent back to Dave, BUT then gains import duties into Australia (I believe).
Dave refuses the huge $$$$$$$$$$ import tax bill etc.
Hence the $15,000 scope really will be put into a dumpster, near some duty collecting bond warehouse.
...So I won't/can't enter.
It looks a very nice scope. But £3650 would be way over budget for me.
P.S. I object to incorrectly filling out custom returns, so that would NOT be an option for me.
REALLY, countries should allow people to genuinely win prizes, TAX etc free. In the same way, many lotteries are tax free. But I guess such a mechanism could be misused, so it is a difficult dilemma.
Ideally (as others have said), the company, kind enough to offer the prize(s), should pay all costs to the winners doorstep. Except countries which are being way too unreasonable.
E.g. Good luck sending it to North Korea, via the USA. In the current climate.
