Green Shield Stamps - Wikipedia, the free encyclopedia
The tobacco industry was dominated by the giant Imperial Tobacco (Wills and Player's). In an attempt to gain market share, smaller rival Wix introduced cigarette coupons with their Kensitas brand in 1956. Coupons were given away with the cigarettes and could be exchanged from free gifts, similar to the Green Shield Stamps scheme.
Coupons were not new. The tobacco companies had used them in the 20s and 30s, but a coupon war saw such expensive gifts given away that some in the industry thought they were selling gifts rather than cigarettes. A mutual agreement not to trade coupons expired in 1956 allowing Wix to revive them.
