Always exercise some caution (and a little healthy skepticism) when someone sells (along with his or her "wholesale" merchandise) tips or newsletters on how to "get rich quick" or "make big money" on eBay. Legitimate wholesalers are there to move goods quickly from their warehouses to retailers. Their business is not to teach you how to "make it big" on eBay. And before you stock up on anything, consider this bit of wisdom from Danny Goodman (the guy in charge of merchandise for Dodger Stadium): When a vendor told him that an item would "sell like hotcakes," Danny replied, "Hotcakes don't sell at all in stadiums."
