Here is the latest and greatest Shop for Free list for Target and Walmart stores. These prices can vary from region to region so you may not find the exact same deals. These are items you can get for free or practically free after coupon!
Thanks to Passion for Savings for her help with Walmart.
Note Target changes prices on Sunday and Walmart changes on Tuesday. These should be ongoing deals (unless otherwise noted) except they can occasionally change things up on those days.
