If you wish to support things that I've done, or show appreciation for any of software or services I've hosted or created you might consider dropping me a quick email.
In the past I used to maintain a Wishlist, hosted at Amazon.co.uk, now that I live in Finland ordering things from the UK has become difficult as a result of Brexit.
If you absolutely wish to send me something monetary I'd suggest that the most useful thing would be vouchers for Amazon.de, or Amazon.co.uk as a secondary choice (because once again there is liable to be delivery-issues with anything purchased from the UK.).
Either of those can be delivered via email, to steve@steve.org.uk
