I'm not sure how this tip is money saving, but it's a GREAT tip that I love so I thought I'd share it anyway!
You know those little plastic cups that you measure your laundry soap in? You know how they get nasty and goopy and gross? Well, when they get gross, simply toss them in the wash with your clothes! They won't get ruined and it washes them out while washing your clothes.
Great tip, huh??
Once again, not sure how this saves money, but oh well. Happy savings to you anyway! :)
