Reader Andrea has informed me that you can get FREE Arm and Hammer Essentials Detergent at Babies R Us (or Toys R Us) right now. It is on clearance for $2.98 and they had a $3/1 Q in their ad this week. Now that's a nice freebie! And it is eco-friendly deterget too ;D
I can't verify that it will be on clearance at all stores, but it is certainly worth a look-see. Andrea found the deal at the Western Hills, Cincinnati store, for the record.
