I was always trying to get a good deal on video tape in the 1980s and went dumpster diving more than once trying to find old tapes to reuse. Sadly that usually didn’t pan out and in the end I had to spend my hard-earned pennies on new tapes from places like K-mart and Caldor.
In late 1985, Wal-Mart ran this commercial advertising RCA blank tapes at two for $9. That seems like a pretty decent price, although I think I picked them up more cheaply at times. Especially when I bought them in batches of 6 or more.
