When I was first getting into D&D back int he early 80s there was an explosion of Sci-fi and Fantasy books to hit the shelves in it's wake. For me this was a great time and one I have talked about before: "Reflecting on D&D - Sometimes you can't go back".
Friday I was driving home past a closed Border's, the company that had bough Waldenbooks and it made me think of my now mostly underused Border's Rewards Card in my wallet, and all the cards that came before it. But the first one, the one I was "proud" of, was my Waldenbooks "Otherwords" card.
For me being part of the Otherworlds Club back then was part and parcel of the D&D experience for me. Back then my FLGS ("favorite local game store" for those new here) was Waldenbooks in White Oaks mall in nearby Springfield Il. This card (which my dad laminated for me) allowed me to get 10% off an Sci-Fi/Fantasty and D&D book I bought! Given the taxes at the time that pretty much meant I was paying just under the price on the cover. Sure, not a great deal, but when you are 12 and the money for D&D books comes from your paper route then that is awesome.
The Otherworlds Club had a little newsletter call Xingals that I used to enjoy the heck out off. I would have upcoming releases and I'd always be thrilled to see the latest D&D book on the back.
Sadly, the Otherworlds club is no more. It was replaced by successive book clubs at Waldens till Waldenbooks itself was replaced by Borders.
It has been said that the Golden Age of Sci-Fi/Fantasy is 12-14. Well for me that was 1982 to 1984 and the Otherworlds Club was my ticket.
Today I have frequent buy cards at two different game stores, discount cards for Borders and Barnes and Nobles and of course my RPGA card. But the Otherworlds card was the only one I ever laminated and carried with me all the time.
