This is my first method share on here, hopefully you guys appreciate this and think it's worthy haha. 1) Sign up to some affiliate programmes ( health / weight loss... you know the kind) where you get x% commision per sale. 2) List these products at a higher price on your preferred selling platform. 3) Once orders come in you buy the product through your affiliate link and ship it out. 4) Enjoy your profit from the higher selling price and the commission you'll get back from the affiliate program. 5) Rinse and Repeat. Hope this helps people.
