I found an old carrier for 45rpm records at a garage sale (like the ones girls would take to sleepovers in the 50s and 60s). It was completely filled with just about every Elvis Presley 45 and 45EP (extended play--four songs instead of two) ever made--mint condition most even had picture sleeves instead of the regular paper sleeves. She had them priced at 5 cents each, I bought the entire box for $2. I paid for an entire year of college (tuition, books, living expenses, fun etc) with the proceeds.
