I agree with Good@Sabacc - idea 3 is bad, but the others all sound really nice. And, to be honest, I agree with everything else that he said, too!

But, I do have some suggestions about your site, and what you could do to make me choose your site over a different UK reseller, or the company's website. I know this is an obvious one, but one thing I would want to see is competitive prices. For instance, cards4magic is one of the cheapest UK playing card shop sites that I have found, yet it is selling Fulton's (which are less than $7 on the D&D site) for the equivalent of about $11. Once you've factored in that they are probably getting a nice discount for resellers from D&D, they could potentially be making a 100% profit on each deck sold. Now, I know that you do need to factor in the shipping costs from the USA, but I think there's a good chance that you'd be able to have more competitive prices, while still making a nice profit.
But to be honest, the main thing that I'd want to see is discounted shipping, and possibly even something like free shipping for orders over £X. I've seen that on a UK site before, and it immediately makes me want to pick some decks up from that site. Shipping from the USA is so expensive when it comes to just a couple of decks, that the chance to be able to spend your money just on decks, and not have to spend some of it on the shipping, is really great.
Of course, I don't expect you to have decks for sale at the same price that D&D/Ellusionist/theory11 have them for, as I understand that the shipping for large quantities of decks would cost quite a bit. What I would want to see is the ability to get the decks plus shipping less than or equal to the decks plus shipping from a US site. And the prospect of free decks would make me even more likely to choose you over the D&D/Ellusionist/theory11/what-have-you website.
I'm not sure if I've explained myself very well - I've just got back from a two and a half hour History exam, and my words seem to be making less and less sense. But I hoped I've outlined the main points well.
