In return for shamelessly lifting the link, I should point out that their fine magazine is now available in all good newsagents. By direct implication if your newsagent doesnt have it it is therefore less than good and you should not shop their. If they are that slip shod about magazine procurement they may also not wash their hands before making your breakfast roll - not the kind of thing you want as a pandemic is about to kick off.
