I have just launched a skincare product on amazon. I need someone to buy the product and leave a review, for which I will reimburse you for the product and give you $15 on top (easy money).
I will then give you $10 for every person in the US you can get to do the same, so if you have some friends or family, you can give them all a free skincare product (they get reimbursed too) and get paid for it.
So if you know 20 people you can message and ask to buy the product, you'll get $200 easy money. No limit to how many people you can get.
