You may use this page to pay an amount different to the annual subscription.
PLEASE use it with care, refunding over-payments is adminstratively complex and
results in losses due to banking charges(!).
You are advised to only use this form to pay an agreed invoice or pro-forma
invoice.
If you do make an error, then please contact us as soon as possible to see if we
can remedy matters before the transaction is finalised by the bank.
Despite the above caveats ... the only real danger is one of mis-typing the amount
in the box below and then confirming it by clicking on Submit and
then confirming it a second time on the bank's page.
For enquiries about back issues, please contact us.
If you are apaying an invoice, please quote the invoice number. (Even if you are 'known' to us, we regret you must still give an address -your credit card address- for our bankers 'comfort'.)
We see the information on this page, but once this is complete you are passed to our bank's computer and we do not see your card details.
