I recently purchased a storage unit with over 2 million sports cards!! With thousands of stars and rookies complete sets And hundreds of unopened boxes .I had no idea what to do with them ! I've decided to sale them in lots of whatever can fit into large flat rate boxes full of cards. Each lot will include as many as I can fit or more cards plus cards in hard plastics .
