Am I wrong by disobeying the store's policy?

I get coupons each month for a large grocery chain store. I don't use all the coupons, but hate throwing them in the trash because I feel others could use them.

So I place the coupons I don't want by the item in the store.
An employee saw me doing this and said it's against store policy to allow other customers to have coupons.
I told them to call the police on me because I'm going to continue sharing the coupons instead of throwing them in the trash.
