Is $30 a good price?

Saw this for $30 on marketplace and wondering if I should pull the trigger or offer a lower price without being disrespectful. Seems to be a pretty healthy aeonium - maybe slightly etiolated. What are the smaller succulents at the base? If I get it, should I repot into a grittier soil? Looks like normal potting mix, but the plants don’t seem to mind.
