Here is a fun (and free!) idea to spread some kindness in your area! Have some leftover coupons that you don't plan on using? Tape them to the corresponding items in the store with a kindness card! It's also a lot of fun to give a stranger a coupon in person - if you see someone with an item in their cart that you have a coupon for, ask them if they have a coupon and if not pass along the coupon and a kindness card! I've gotten nothing but good response from it - who doesn't love saving money?!
This works especially well with catalina coupons you may receive at the register but don't plan on using. I received a high-value $15.00 off Enfamil coupon but don't use the formula, so I taped it to a canister in hope of making a mother's day. :)
