Ebay Search: Absolute Batman 1 / “Absolute Batman 1”

Been tracking AB 1 on ebay for some time. Yesterday and today when I type Absolute Batman 1 only trades and non 1 issues come up. If I type “Absolute Batman 1” many first prints come up. What’s going on not sure. Also, someone sold a 4 set books lot for $5k. 3 first prints and 1 Spawn 301 Alex Ross SDCC cover.
