Low - Guys selling comics on FB.
Don't say "make an offer" & then get upset when a reasonable offer is made. Put a price & say negotiable.
Don't sell comics in bundles. Take time to mark them individually.
If you want to sell stuff, be ready to drive down to your local Postnet for one comic. Not everybody lives in driving distance of your place.
& check what the stuff is worth, just because you say its "vintage" does not means its worth anything
& thats just the comics, don't get me started on the figures lol
