I hope I am posting this in the right place. I have recently started collecting comics again. I collected them when I was younger but stopped several years ago. I have between 1,500 and 2,000 in my collection. I just wanted to know how most of you stored you collection. Mine are currently in comic book bags with the cardboard backing. Then I store them in a large rubbermaid container. Does it hurt to lay them flat or should I get the cardboard boxes that store them upright? How do you all store them. Thanks.
