Everyone recommends dropshipping but analyze: is dropshipping still viable in 2025? Map the dropshipping reality: competition, thin margins, customer service nightmares, supplier issues. Calculate: if margins are 10-20% and ads cost 15%, what's actual profit? Show me the dropshipping truth: saturated market, race to bottom on price, high failure rate. Give me the alternatives: if not dropshipping, what e-commerce model actually works? Include: why dropshipping worked in 2015 but doesn't in 2025, what replaced it, and whether I should skip dropshipping entirely.
