To be honest it is probably legit.

It's also likely its either a small-time firm, and/or a cover-up for those running shall we say questionable stores to offer easy payments. We are all aware how hard it can be for these music stores because of its 'gray legal area' outside Russia/license issuing country.

As for the post code/address issue, their contact number is for outer London, which matches the postcode.

As ever, with whatever website you give your card details to, just make sure you check your bank statements on a regular basis.

I'm not 100% sure but I also think that the SSL cert issuer or the company that actually provides the payment solution should run checks on them first before issuing it?
