With my husband, I just keep talking about the money. When I talk about the "stuff", he has scary visions of the house filled with lots of things we don't need.
He also told me that he doesn't want me to be stressed out trying to save money. I think it makes him feel like he's not providing enough. Of course he is; I just like SAVING it for US!!
To help him have the experience, I gave him a list of things he knows we need and a handful of coupons and asked him to do the shopping. When he saw how much we saved, he was on board!
He's such an awesome man!!
