Some of my favorites are:
$1/1 Target Up&Up Oral Care Item = free floss
$1/1 Target Up&Up Cleaning Item = free scrubber sponges, cheap cleaning products
$1/1 Target Up&Up Laundry Detergent = cheap detergent and bleach
$1/2 Market Pantry® Dry Pasta AND Pasta Sauce = often found on sale for $1 each
-$1/1 Up & Up® Cough and Cold Relief Item = cough drops are regularly $1.39
And also remember, its the end of the month, so print those coupons! Many of them will either disappear or reset.
