Why no stuffers?

We always complain about the lack of lists. Strange how few bag-stuffers and savings coupons we use. These require no lists, and goes to customers with the highest possible R (recency). Actually, except for takeaways, especially pizza parlours, who do these all the time, I can’t remember anyone using putting these into my bag along with my purchase.

Ok, banks and credit cards send them, but the not in mind boggling numbers. I wonder why we stay away from stuffers. I’m sure it’s not some high principal against ‘junk’, because we do so many junk calls, SMSs and email.
