1958 Southern California.
10 gallons of Super Shell was $3.33 or 33.9 per gallon. Regualar Shell was 25.9. We would have constant "gas wars" and would see prices at 19.9 plus we had to give out Green Stamps which could then be redemed for prizes. One of the best stories I remember about the stamps was traveling, probably in 1969 or 70 and hearing the truckers talking on their CB radios as they got close to Las Vegas talking about how many books of stamps they had collected on their cross country trip and how they could use them for "favors" from the ladies of the night in Las Vegas. Stamps started disappearing in the early '70's. I never collected enough stamps to "use" in Las Vegas. Thank God
