My old work did a Secret Santa with a $10 limit, and I didn’t know my recipient well. Last minute, I spotted an old copy of Oliver Twist in a second-hand bookstore for $10 and bought it.
On the day of the gift exchange, I noticed a woman crying and heard people asking for her Secret Santa. I went over and revealed myself. She hugged me and tearfully explained that 10 years ago her house burned down with all her belongings, including that very book. The copy I gave her was the exact same edition, weathered in the same spots, as if I had grabbed it off her shelf before the fire.
