Will my target audience realistically buy this now, or at a different time? Be sensitive to sales cycles and seasons. Maybe you should avoid holidays (when people are away from their computers, like July 4 in the U.S.) or maybe you should target holidays (like the day after Thanksgiving), but know the difference. Again, know your audience. Plan your content accordingly.
Amazon offers a service called Fulfillment by Amazon (FBA), which can be extremely useful for arbitrage sellers, or others selling their own products. If you opt for FBA, Amazon will store, pick, pack and deliver your products. That means you can scale your arbitrage business quickly as you don’t have to store products in your own home or waste time with postage.
