Kmart has Purex Detergent on sale for $2.49 through 5/5. Here is how to get a much better deal:
Purex Detergent 33 loads $2.49
Use $1 Purex Detergent coupon (zip 10004) or $1 Purex Detergent coupon (zip 33234)
Final Price: $1.49
This deal runs for several weeks, so grab all of your coupons now and stock up the next time you visit Kmart! Anything under $2 is a stock up price in my opinion!
