In the spirit of the holiday giving, help out others and share the coupon love!
If you have coupons for products you aren’t going to use at the store, try and spot someone with those products in their cart, then give them the extra coupons. It always puts a smile on their face and leaves them with a good impression of couponers! You can also leave coupons nearby the applicable product (or tape them on so they don't get thrown away), hand a coupon to someone in line behind you, or drop off extras at a coupon swap box.
Note: Avoid leaving any Internet printable coupons. Sadly, there have been stories of KCLs sharing their printables, only to have their recipients make copies of them and use them; then the unsuspecting KCL's coupon printing account is suspended because of fraud. Also avoid accepting or using any third party printables where the validity of the coupon cannot be established.
