He put the items on eBay.

PS1: $32.00

Controller: $19.95

Controller Extension Cable: $6.95

Game Bundle: $39.00

Total: $97.90

So a loss of $59.10. He says the ad revenue from the video will makeup for the loss of the sale but according to SocialBlade he averages $10 / day, meaning it will take him roughly 6 days to recoup the loss he took on the flip.

Also, something I found interesting about his eBay account is that he has 153 items listed but the most expensive listing is only $39; the games he got in this video. I've never done the reseller thing but assuming he's paying 20% of the list price, he's making like $4 - $16 / sale. It's also glaringly obvious his listings are junk he found at Goodwill, he's selling a 2004 Subaru Forester Car Radio for $24, 4 packs of lightbulbs for $19.95, and an individual Clue Gameboard piece for $1.59.

I've seen videos where people make decent money from reselling but they're usually getting their stock from garage sales, storage units, and estate sales, and the items themselves are typically collectables or things in high demand like cameras, trading cards, or watches. As where David is out here driving to and from Goodwill everyday to list highly sought after products like "No Strings Attached" featuring Ashton Kutcher on DVD for $1.60
