I always buy household cleaning and laundry items and  on the cheap. Otherwise, I just use Vinegar (a little secret I learned growing up, Vinegar is the all purpose cleaning solution!)

My local Dollar General usually has the 20 ct for $1.00, that would make it $0.25 after coupons. Hope they have a BOGO offer soon, woohoo!

Look for the $0.75/1 Snuggle Fabric Softener Liquid or Dryer Sheet 10/2/2011 RP Insert (exp 11/13/2011)
Final Price; $0.25 (at Dollar General)
