The forum post I read got me curious about other K Mart/Topps sets. A look at the Standard Catalog gave me four more 33 card boxed sets. They came out from 1987 - 1990.
That led to a thought about other retailers that worked with Topps and I've come up with a list that includes seven more stores....Kay Bee, Woolworth, Revco, Rite Aid, Toys R Us, Ames, and Circle K. After the '82 K Mart set, these sets were produced between 1985 and 1993.
I don't know if Topps if its bad luck to do business with Topps, but of these eight retailers, four (Ames, Woolworth, Revco, and Kaybee) are dead. K Mart and Toys R Us have declined steadily (Walmart passed KMart as the #1 US retailer and Toys R Us as the #1 toy seller) and Circle K has gone through bankruptcy. Only Rite Aid seems to have escaped the curse of Topps.
I'm planning to try to pick up all of the boxed sets put out by these various retailers. Most are 33 card sets, though a few have 44. I'm also keeping my focus to the Topps sets. Fleer worked with some retailers too, but right now I'm going to pass on them.
Here's the list of retailers and their Toops boxed sets that I've come up with:
Ames: 1989, 1990
Circle K: 1985
K Mart: 1982, 1987, 1988, 1989, 1990
Kay Bee: 1986, 1987, 1988, 1989, 1990
Rite Aid: 1988
Toys R Us: 1987, 1988, 1989, 1990, 1991, 1993
Woolworth: 1985, 1986, 1987, 1988, 1989, 1990, 1991
That makes a total of 28 different boxed sets. Right now I've got 24 of them with three more on the way. They were fairly easy to find, with just a couple that required a bit more sleuthing. Most could be had for a couple bucks, some even less, a few a bit more.
A couple more things...
...Some of the earlier boxed sets not only came with the cards, but they also had a stick of gum. A couple of the boxes I bought were still in their original cellophane wrap, meaning...
...Topps also worked with some food companies (Drakes, Quaker Oats, and Purina). At this point I'm skipping them and sticking to the retailers. Some day I'll go back and add them.
