"PSA makes up the VAST majority of this business and there was literally no way for CSG, which was JUST getting off the ground, could have anticipated the amount of cards at first. "
Again. Any with 2 Brain Cells would have taken one look at your competition - Seems like you're unaware, but the massive influx of cards didnt just happen to PSA. It also happened to BGS and SGC. So , again, one look at your competition, which any business worth their salt would have done, would have quickly shown how bad of an idea cheap bulk was. Especially for a new company not yet scaled to handle bulk subs.
"literally no way" - is just not true, sorry... And its also a bit dramatic.
