Martin et al,
The UK edition only went on sale this Thursday 21st and the subs copies posted off on 20th, so they are likely to arrive Monday/Tuesday of this coming week for UK subscribers.
If your copy has not arrived midweek, please email
support@soundonsound.com and it opens a Zendesk ticket and a replacement mag will be posted out (which goes via a more expensive, non-bulk delivery, Royal Mail service, so that copy usually will turn up).
Why do we not use this RM service all the time then? Well it would triple the subscription cost to end users and thus make them unviable if we did. Magazine publishers use the RM 'magazine' bulk delivery service - which used to be good...
It does take longer to get mags into the EU since a certain event happened.
US/Canada mags are printed separately in the USA and typically don't finish printing until a week after our UK edition, as the layouts are made from the UK versions, new US adverts dropped in and uploaded to our US printer, hence US/Canada mailouts are always a week later too and it's a much bigger country so delivery takes longer there too.
