Thanks, Dien.

I also found Don's response to a similar question in another thread. He mentioned the use of QR codes, stickers and some other value-added items.

Interesting how such a simple idea can lead to so many other paths of opportunity (and effort!).

When I was reading last night, I thought about co-op mailings using the EDDM program from the USPS (Bob Ross) ... I guess there's lots of ways you can take this ...
