Postcards are dead?

Got this email from my ad agency:

SAE Automotive Engineering Intl Postcard Deck is offering a discount for a
card in their May deck. Regular rate is $1955 (net), discounted rate is
$1249.50 (net). First come, first served. Closes now. Let me know if
interested.

Are card decks dying as a form of advertising? My last effort at card decks returned ALL JUNK!

Even right now, I am looking at a lead report from a trade-pub with four names on it, and they all look realatively legitimate. But there is no "Kzoptronilis" company that I can find. Oh, well, well send it out and see.
