Your BAR story and my STG story both say it’s a good idea to attend as many of these “buy back” events as possible. Never can tell what kind of treasures might be available. Sort of like buying a lottery ticket.
I had an absolutely great time at the three Phoenix “buy back” events that I attended.
I wasn’t buying, except when it was directly presented to me, and I still got some great deals. Some people got incredible deals - and still a great deal of treasure was needlessly destroyed, simply to make political theater.
