From $50 at garage sales to $600/month on eBay — here's my system

It started with a garage sale find — a vintage KitchenAid mixer for $8 that I flipped for $95 on Facebook Marketplace the same weekend. I was hooked. I spend Saturday mornings (2–3 hours) hitting 4–6 garage sales. I only buy items I can sell for at least 4x what I paid. My focus is small kitchen appliances, name-brand handbags, and vintage glassware. I research prices on eBay's "sold" listings before I buy anything. Average month: I spend $80–120 on inventory and net $500–700 in profit. Nothing life-changing, but it pays for my groceries plus some. And honestly, I enjoy the treasure hunting aspect.
