I've discovered that Pextons on Bishy Road stocks the 'Golden Fleece' style scourers my Mum especially likes, and which seemed to have vanished from the market. The chap behind the counter says these are reintroduced, and they'll always stock them. I'm going to see her next weekend. I've bought two packs to take her. What a glam present!
Also, although they can't cut MFWHTBAB's odd chubb key, they've suggested someone who can, on Walmgate.
