Plants don't have a shelf life @ a BBS. Succulent or otherwise. They're kind oflike produce, they just hope most of it sells before it goes bad. Going to one to check the plants is mysterious, there may or may not be some healthy plants that you want that day. You could go often to find the good stuff before it has a chance to become unhealthy, or go rarely and select from what looks good. Or go to an owner-operated store, if there are any left in your area, where they care whether you show up or not.
I don't see any point in complaining (beyond a post like on these discussions) for several reasons. First, if there were more knowledgeable people there &/or enough people to care for plants, the prices would be higher. Second, when someone has to field a bunch of complaints about something, it could be decided that the category is more trouble than it is worth. If that happens, there could be no plants. Third, what if someone who is already stressed and overworked gets some kind of demerit, or worse?
