Website is still not working for me
We have had a few issues and these bugs are being fixed as we speak.  Hope to have it up tonight.
Good luck mate, I think your'e going to need it 

My advice, should have done it the other way around, got VAT registered ASAP, it doesn't cost you anything to be VAT registered and do everything on the up and up.
There is no Import duty on computer equipment coming into the UK, only VAT.
So you buy at whatever wholesale discount you negotiate, you pay the VAT, which you claim back anyway.
Then you sell at the RRP +VAT and your cut is the difference between the wholesale price and the retail price. Then you give the VAT you charge to the tax man.
Punters will be fine about it, they have to pay VAT anyway on imported stuff. Even KnC charged VAT on all their miners for EU sales.
In the EU there is no getting out of paying VAT, eventually.
