I'm sorry some of the papers you bought didn't have inserts in them, but Please don't be accusing someone of something that you have no proof of.
I agree with Amylynne01, there is no guarantee when you buy a paper that the inserts will be in there. Trust me I know. I get my inserts from a guy who delivers to a few small stores and if they get shorted guess what? its the stores papers that get shorted not the home delivery. I know, I have had many many store papers and have had no inserts in them. So please don't put the blame on someone stealing them.
Most stores have their stacks of papers right in front buy the check out lanes and it is not that easy to pull the inserts out without being noticed.
