Resell :StatTrak™ AK-47 | Vulcan

The AK-47 | Vulcan is always in high demand. A quick way to make easy profit is to resell the StatTrak™ AK-47 | Vulcan (Minimal Wear).

The initial cost of the skin is $163USD, but you are able to resell it on the steam market for ~$230-$240USD.

After steam taxes, if you were to sell at $230USD, you would have made ~$40USD.

You can take it one step further and turn that into real money. To do this you would want to find probably 2-3 items which hold it value in the steam market and OPSkins. Hence, if you were to purchase 2 items at $100USD each and resell on OPSkins for $100USD each. You would make $90USD from each transaction which equates to $180USD. So you could make roughly a $15+USD real money profit or a $35+USD steam profit.
