So, I didn't start purchasing Plink! Until I moved into my apartment 5 years ago. One day I came home from work, and there was a smell. I took out the trash, next day still there. So I talked to my sister. She said "You have a garbage disposal, buy this stuff." Alright then. I purchased it, and amazingly the smell went away. I signed up for subscribe and save on Amazon for these as well, Even now, owning my home, I can tell if I don't use these as often as I should. When I do though, it makes a world of difference!
