I feel like the particular cards I have been flipping have gone pretty well for me. I know last year I was flipping a lot of silvers and golds and would make 100-150 per flip. I would be doing 5 transactions at a time per card. This year I've only been flipping 2-3 transactions per card at a time but my profit per card is anywhere from 300-1200 per card.
In the past week I've finished up NL West, AL West, and just need Acuna to finish out for Johnson SS
