This is gold. Especially #8 on velocity. I've been tracking 30K+ eBay listings for months and the data backs this HARD: Cards priced at 85-90% of market that sell in <48 hours outperform cards priced at 100%+ that sit for weeks — even when the slow-mover eventually sells for more. Why? Because that capital is DEAD while it sits. You can't reinvest it. You can't buy the next deal. You're just... waiting. I tracked 200+ "underpriced" listings (15-25% below recent comps) and 89% sold within 72 hours. Meanwhile "full price" listings had 31% sell rate in the same window. The winners aren't the people with the best margins. They're the people who turn inventory 2-3x faster. Your point about sourcing (#5) is the unlock most people miss. Retail is a sucker's game. The real edge is buying collections where the seller doesn't want to piece it out and you can pay 50-60 cents on the dollar for the whole thing. Then velocity + volume = actual profit. One addition to your tax point (#6): If you're doing serious volume, consider getting a resale certificate in your state. Lets you buy inventory without paying sales tax upfront. Saves 8-10% immediately on cost basis. Appreciate you dropping this. Most "how to flip cards" content is garbage. This is the real math.
