Arm and Hammer laundry detergent as low as $2.50 each at Kmart with double coupons.

Another idea for Kmart double coupons this week:

Buy 8 bottles of Arm and Hammer laundry detergent 2/$7 ($28 + tax)
use (4) coupons (you will need 2 computers to print 4 coupons)

$28 - $8 (they double with $25 purchase).

Total is $20 + tax for 8 bottles - only $2.50 per bottle!

Remember that you can only do this once per day and up to 5 coupons max double (4 like).
