The snuggie which is basically just an oversized robe that you wear backwards. And people really fall for it. How do they not see its the same thing as the robe they have in the closet just a larger size? https://www.getsnuggie.com/ Or worse yet...Shamwow! Its a towel, people! They fool the masses by comparing it to paper towels, but its really just a regular old towel. They try to sell you that you spend 20 dollars on paper towels per month, but who will wipe their mouth with a shamwow after they eat? Its about as logical as having your bath towel at the table to wipe your mouth. https://www.shamwow.com And dont even get me started on these ab machine scams. $120 to get you to do situps. https://www.abrocketsale.com/ Do you know any others?
