As a child I remember my mom collecting the S&H green stamps. Today we have store specific rewards cards that are kept in balance on computers.

 Are there any replacement systems like the old S&H or box top and label mail ins?

 Of course back then the items you could get were good quality. Now days, probably aint worth the postage. But curious what is still running that makes one jump thru their hoops to get things for free or low dollar.
