eBay Australia — actually, not just Australia, but in my category, the top sellers are pricing their items at $15 AUD. That’s exactly what I pay just to ship a 0.3kg package (20x10x6cm) via Australia Post (2–6 day delivery).

They list their location as Australia, so they’re shipping locally. I’ve asked multiple 3PLs, and the cheapest I can find is around $8–9 AUD for tracked shipping — and that’s with strict size limits.

How are they pricing at $15 and still making money? What am I missing?
