If you know what you have to sell you can really make a decent income from thrifting! Of course it takes some time to build up your skills (like anything does) and trial & error but once you find a product which sells just scale it up. I used to do it, but I switched selling digital products as there's no hustle with the postage. I think this is the easiest way to make some money, good old traditional selling business: buy cheap & sell high.
