I love pop tabs!! The reason I save them is because my son passed away at 41/2 and I set up a foundation for him and saving the tabs are the big thing we do and that's because we were stuck far away from home and I didn't wanna leave him so the Ronald McDonald House let me stay there for free they help so many people out with sick children! Once I take them there they trade in for cash and that's how they run the Ronald McDonald house! But I do believe there's lots of reasons people save them!
