Boas are extremely common, in case you weren't aware. More than half the ones I find on CL are because "it got too big", "Spouse/roommate is afraid of it", "No longer have time for it", etc. In other words they want it gone. Many ads even said FREE IF GONE TODAY MUST GO ASAP. Well if they want it gone or want a good home for it that should be their goal, not getting their money back from buying it.
