Blimey Weks, there is a pic in my Boots book just like that one.
Truth is, while I just about remember beer kits being on sale in Boots (in Bradford they were next to the cafe—Christ, I just remembered that Boots used to have a cafe!) by the time I was old enough to think seriously about buying one (15?) they'd stopped doing them. I also seem to remember Morrisons doing a reasonably serious range, including some of those brands from your Boots image — Geordie and Edme in particular, both of which are still in production.
Nothing like a bit of nostalgia for a Sunday evening, eh!
