Mattel’s Masters of the Universe on Sale at Walgreens in 1986
July 30, 1986. The South Florida Sun of Fort Lauderdale, Florida offers up this Walgreens coupon to get Mattel’s Masters of the Universe action figures for only $4/each. This ad is one of many early warning signs that the brand was in trouble; as we know, 1987 sales of Masters of the Universe were so weak that the line came to a close.
