A small bookshop, Chapter and Verse, in Bolton, near Manchester. They sold imported, cent copy Marvel and DC titles that weren't ordinarily available the UK and charged 35p for a standard-sized issue, which was three times the cover price for the distributed pence copy comics received by the newsagents three months later.
Lots of overpriced back issues but only from the previous four years or so to 1973, after the picture frame Marvel era, with lots of Giant-Size titles but without the most significant one, of course.
I went there for about 18 months and then started going to comic marts, found cheaper dealers and a wider range of material, and never went back.
