I'll confirm again with my presser who dropped them off locally, but I specifically requested not. I suppose he could have screwed up, but I was billed for 25 comics at $455 (25x$18+$5 submission fee) upon receiving back in January (not after pre-screen), did not have extra TAT for prescreen (confirmed by the other submissions that were also dropped off at the time by the same presser), and nothing about pre-screen was mentioned in the return form. So hopefully you can see why I'm confused.
So still at a minimum I'd need a partial refund for the rejects.
