The only thing I know to be unlawful about the site is that you have no contact details - your whois says it's a "non-UK corporation", is it really? It sounds like it's just you?

Anyway, commercial operations in the EU must have contact details listed to comply with the EU E-Commerce Regulations (2000), you also need to say if prices include VAT. Many, many websites fail on this but as you're sticking your neck out it seems it's something you could immediately be charged with.

It's complex though - http://www.out-law.com/page-431 gives good details.

Note the regulations are written so as to apply to commercial activities on the net, this includes personal websites, for example.

You can probably avoid that one by being wholly based outside the EEA and having no controlling staff within the EEA.

This isn't legal advice.
