I was spending 2+ hours a week just pulling comps. HobbyMetrics cut that to nothing. The P&L tracker alone is worth every penny — I finally know what I'm actually making after fees.

I had three different spreadsheets for raw cards, graded cards, and sold cards. Now it's all in one place. Game changer for auction prep — what used to take 2 hours takes 15 minutes.

The fee calculator changed everything. I kept thinking I was more profitable than I was because I wasn't properly accounting for eBay's cut. HobbyMetrics showed me the real numbers.
