Butane lighter review: Selling lighters to minors

I allowed my 14 yr. old to ride his bike with his 14 yr. old friend to the dollartree store in Pennsville, N.J.
After my son returned home, I found his receipt on the bathroom sink and just being nosy to see how much candy he purchased I was shocked to see a butane lighter was purchased. The register should prompt for I.D. or the cashier should be smart enough to know that you shouldn't sell lighters to 14 yr. old kids if not with an adult. Needless to say, they admitted to doing this before and buying lighters previously at the same store. Is there anything that you can do to prevent this from happening again? Children are making purchases of products that are harmful to them and to other people. I went to the store and talked with the manager that said they had no control of what they can or cannot sell to children. She said that the only thing that they couldn't sell to a child was an energy drink, but they couldn't stop them from buying lighters? She sympathized with me that she agreed that the company should do something to ban minors from buying these products, but her boss said there was no control over it. I do not agree with this, as I work in retail and my store's registers prompt for check I.D. on paint, glue and other harmful items. And if there was a child or teenager that would try to purchase a lighter or anything harmful that didn't prompt for check I.D. the cashier would surely stop the sale without adult supervision.
