Preventing Grails from Happening

This year I got into a delightful rabbit hole that introduced me to so many great artists, albums, and songs. But not all the albums I wanted were easy to find, and some that were on the list were going for a pretty steep price. Vigilance, however, paid off when by some strange occurrence, all out-of-reach items suddenly began to show up for sale for cheaper than previously listed. Mine! Mine! and MINE!
