So many YouTube videos about:

-drop shipping

-having third world countries produce your generic "merch" for your "brand"

-flipping items from Goodwill or garage sales on EBay/OfferUp/Poshmark/Mercari,

-buying in bulk from Costco and piecemealing it out onto Amazon Marketplace

-buying huge pallets of returned Amazon items and flipping them on the aforementioned sites and apps

Just a cycle of churning plastic nonsense
