Choosing Dropshipping Products: Competition, Velocity, and Margin

product selectionsourcingcompetition

Every dropshipper starts the same way: find a product with a low Amazon price and a high eBay price, list it, and wait for orders. Most realize too late that the gap everyone sees is the same gap competing with, and margin evaporates from there.

Red flags on first look

• Too-good-to-be-true margins. A $20 item costing $5 on Amazon selling for $35 on eBay means 20 other sellers had the same idea. Price floor is real.
• Super high category competition. Electronics, toys, apparel — high-velocity categories where a dozen sellers with similar setups all race to the bottom.
• Volatile Amazon pricing. Items that spike $10+ on any given day are either desirable (high competition, price wars) or unstable (supplier chaos, frequent stockouts).
• Serial out-of-stock on Amazon. If an item goes OOS, sells out again, bounces between stockouts and sales, you'll spend more time managing pause/unpause than fulfilling orders.

What actually works

Niches where information asymmetry exists: products where eBay buyers are willing to pay more because they trust the listing details (accurate compatibility info, bundled accessories, verified condition) more than a generic Amazon listing. Niche electronics, craft supplies, hard-to-find older models — places where a 10–15% margin exists because of trust, not just price arbitrage.

And velocity matters: a product selling every 3–4 days at $10 profit beats one selling monthly at $50 profit, because you can actually iterate on pricing and optimization.
