Had a quick look back on the thread, couldn't fnd cigarette coupons. Specifically, Kensitas*.
Only now does it occur to me to wonder why the Kensitas Catalogue (yes young people, really) had consumer goods in it rather than things like oxygen bottles, money off coupons for radical lung surgery or coffins. You know, stuff that would be really useful after you'd smoked your way through the thousands of packets required to amass the necessary coupons.
*Reminded by old film on TV t'other day. Advert for Kensitas fags outside a tobacconist. Hmmm, tobacconist shops, you don't see many of those around these days either.
