If you contacts overseas and enough volume you can often move various electronics for a decent margin. It's pretty involved though. One of the routes I'm aware of involves buying gift cards from Kroger with a high cash back credit card during their frequent events where they offer extra fuel points on purchases. They don't charge activation fees on gift cards, and you can sell the fuel points accounts somewhat under the table on eBay, and then pocket the cash back from your credit card. Then you wait til black Friday or other sales, use the gift cards to buy electronics at discounted prices, and then ship them overseas to sell for a decent markup. It involves floating tens of thousands of dollars for several months though so not quite for your average individual just trying to make some quick cash.
