Yeah. Lots of DC keys are just nowhere near as popular as their Marvel counterparts. We have an Adventure Comics 247 sitting tight as I believe one day...that book will get its mega due.
Do you have bargain boxes? We do really well with our dollar boxes that we stock every few weeks with new blood.
Missed this before, sorry. Yes we actually do $2 on most books as the low and then also 50c for the stuff I just want to blow out. New books go in there a couple times a week to keep it stocked.
