You can get a $10 off credit on your purchase at the Medco Health Store when you use the code MHS10. Shipping is a standard $0.99 per order. Kate shares that she bought $20 in Swiffer products and between the $10 store credit and a $10 rebate offer available Swiffer is offering she will end up paying $1.88 for two duster refills and a bottle of Wet Jet refill. There are tons of other item and no minimum purchase requirement. I am eyeing the baby products.
Update: Use code TENOFF to get another $10 off on a second order. Thanks Dealyo!
