Does anyone know where I can find the "old" Weight Watchers Companion book that was used circa 1994?

Answer 1

Try library book sales, yard sales, shops associated with rescue missions and online bookstores that specialize in outdated books. Some of those websites are:
http://www.abebooks.com/docs/RareBooks/?cm_ven=ggl&cm_cat=au-search&cm_pla=old%2520books&cm_ite=old%2520books&afsrc=1&gclid=CM2usPa_iYwCFR6AWAodr1wVBA
http://www.barnesandnoble.com/used/search.asp?z=y

Also, did you try ebay? They have oodles of Weight Watchers Companion books. You didn't say what you wanted and there are two types: the dining out companion and the food companion. I did not go through each listing to look for the year of issue but here is the link for the ones listed on ebay:
