I remember tv ads for Raleigh, touting the coupons. My parents did not smoke and thus were not involved in coupon redemption.
In our area (San Diego) most gas stations gave S&H Green Stamps. Of the local market chains, two (Alpha Beta and DeFalco's, the latter acquired by VONS in c. 1971) gave Blue Chip stamps and one (Safeway) gave S&H. Safeway had the best meat, but lousy produce, so mom tended to favor DeFalcos, with Alpha Beta as a back up. She ended up buying meat from a local meat market which was superior to any of the supermarkets.
As a result, we had tons of Blue Chip stamps, and a smaller influx of S&H (mainly from gas purchases). We used a dampened sponge as well. Normally you got one stamp per 10 cents of purchase, but both S&H and Blue Chip thankfully gave 10-stamp coupons for a dollar purchase. 50 stamps or five 10-stamp coupons filled one page in Blue Chip books. S&H books had squares to affix a 50-stamp coupon ($5 purchase) but I never saw a 50-stamp coupon issued by the stores we patronized; we received single stamps or 10-stamp coupons. I do remember the stamp dispensers at checkout operated by the checker.
We kept the stamps in a kitchen "junk drawer" in manila envelopes: one envelope for Blue Chips, one for S&H, and one for unused Disneyland ride coupons, which never expired. Filled books were placed in a built in kitchen bookcase (which help mostly cookbooks) until it was time to go to a redemption store.
The redemption I remember the most was the ping pong table, something we normally would not have money for. It either came with a cover or else we got a cover with extra stamp books. It folded for storage and had wheels on the bottom. We stored it in a covered breezeway with the cover on it. However, I don't think the materials were the best, I think it was made of compressed wood chips, and after several winters (despite being stored in a covered location with a plastic cover on it) it began to warp. However, it was a luxury we enjoyed courtesy of Blue Chip stamps, an extra that I doubt my parents would ever have considered purchasing.
