Kmart has a new rewards program called Shop Your Way Rewards. Earn 1% back on qualifying purchases. I know it doesn't seem like much but every little bit helps! You can use your rewards toward purchases and/or apply for them online and receive a cash back check. In addition, each time you present your rewards card at checkout you will be entered to win a K'Ching suprise.
Go here and fill out for your card and read more about the program.
