The only downside is that will probably get stung for import duty & VAT which will bring them back to over £100! (duty applicable to purchase price & shipping)

You don't always get hit with a duty bill, but just be aware that it's not as cheap as it sounds if you do.

I've bought stuff from the States/Japan before and not had to pay anything, but also had a lovely bill arrive when I have bought other stuff in the past.
