At the greeter's station in Meijer (on the "non-grocery" side, if you must know,

) I found a coupon:
American Greetings FREE card with any 1 card purchase (equal or lesser is free), exp 5/31/07
It says mfg coupon, but it also has the Meijer logo on it. No wording like "redeem at Meijer" or anything, just the logo in the middles of the coupon. Can I use it elsewhere?
Also, how do I put the coupons in the database? I've just been assuming that someone would do it, but it makes more sense for me to learn how.
