Sorry, but... what? :)
I reckon prior to their imminent 'woes', Royal Mail was probably their (more costlier) vehicle of choice and all that?. But in light of 'current events', then ... As Ce-Lo once sang in this smash hit song 'Forget You', where he said: "Just because I don't drive a Ferrari, doesn't mean I can't get you there?". Every little helps and all that?. :-)
WOW!. You originally bought a massive stash before the last 'Empire' went to pot (Woolworths). And now you're buying another stash and this current 'Empire' too (Maplins) is going to pot ... Maybe that's a 'sign' for you there somewhere, perhaps?, hehehehehe. ;-)
Arrived today (20 April) by Hermes - not Royal mail as stated by Maplin. Best before on AA batteries - 2023 and for 9V batteries - 2022.
