does couponing necessarily mean you have to use different products ? only whatever is on sale?? for example i use tressemme in my hair for shampoo and conditioner, johnson and johnson baby products, and certain deodorants. or certain foods lol. sorry if it's a dumb question, just want to know what i'm getting myself into before i start!
