Over the weekend I received yet another pitch from AARP, which I have no intention of joining. This time instead of the plasticized paper cards, they sent plastic cards. I recycled and shredded the accompanying documents, as appropriate, and set aside the plastic cards to deal with later.
I imagine that any plastic card someone sends as part of a marketing campaign would probably work, as long as they're a light color on the reverse, and then you don't have so much plastic to dispose.
The best seed tags for free. Next time the AARP mailing comes, I won't be so quick to growl at it.
