Also, Didn't realise that Poundworld were back as One Below.
Not quite, the original gaffer of Poundworld (Chris Edwards) sold up around 2015 and the new owners basically wrecked the entire operation (it went from being a pound store to a fairly poor discount store compared to the likes of Home Bargains / B&M) and it went bust
Chris then got took on by Poundstretcher for a bit but that relationship didn't work out too well as they basically refused to listen to any of his ideas, there was a Channel 4 documentary about it which I'm surprised ever got to air considering what a bad light it showed Poundstretcher in!
Then he got bored of retirement and OneBelow was born with all items apparently £1 or under, fun fact if you go to the one at Bradford Forster Square I believe that is now the UK's largest pound shop!
