India today, Readers digest copies not delivered

The obc domain investor who finds copies of the India today magazine missing often, usually at least one copy a month missing in goa, enquired with the postman regarding the missing issues of the magazine. The postman said that he was delivering all copies of the magazine which he received on time, however it was observed that copies of india today and readers digest were often missing for many of the subscribers of these magazines, who would then complain to him.
Copies of niche magazines and business magazines are less likely to be stolen or missing.
So general interest magazines appear to be more likely to be stolen by someone who knows the postal system very well. Is the theft intentional?
