Genuinely curious how other diggers handle this. When you count lots, shipping, platform fees and the records that sat for months, do you know if you come out ahead? Roughly how many records did you resell last year? How do you track it (spreadsheet, app, notes, memory)? I'm building a small tool for this and want to check the problem is real before I go further. No link, nothing to sell. Brutal answers welcome!   submitted by   /u/DarkCALM_ [link]   [comments]
