Thanks for the encouraging words. ok, maybe I should post a Ask HN to get feedback on this, so that I don't interrupt this discussion. However I do want to ask you if you believe that someone could be incentivized to bring a TV from America to UK? This is exactly what the idea is - but I always thought 'small easy to carry items' (not TVs). But interesting comment. Thank you.
I would guess the main problem with your idea is that unless you can find a way to cover customs logistics you are effectively encouraging people to break the law. How will you cover people needing to pay import duty and taxes on the goods they are bringing into the country?
Good point. What if it is restricted to items bought in duty-free shops? Eg a nice scotch bought in a duty-free for a friend. Is that still encouraging to break the law? [serious question]
