I know this is a couple of days late, sorry.
I live in Marietta, so not too far from you! Local shops around here are Creation Reef (Woodstock), Optimum Aquarium (Kennesaw), Atlantis (Marietta), and Marine Reef (Marietta).
All of them carry plants. I would say to check Creation first. They have a lot more options and tend to always have stuff in stock. They are exit 7 off of 575.
