Well, most pop tabs for money is a scam to some degree. If you saved a million pop tabs they would be worth about $350 dollars. A hundred is worth about 3 cents. That is about what a scrap dealer would pay. So collecting and storing a million of those things take up some space plus lugging them to the scrap dealer. A bit more money could be had in collecting the cans and redeeming them for a nickle per can if your state has a recycling law. Or saving the cans and selling them to a scrap metal dealer.
