If you are referring to the Gold EEO certificates, they are normally mailed annually around the end of February and are based on your upcoming elite level come March. Starting with this year, it seems Marriott decided to mail them out once for the whole year rather than quarterly. Based on posts in other threads here (and my own experience) if you didn't get them last month, you probably won't get any mailed to you at all (until next year's elite change-over occurs.)

But all is not lost. :0) You can access the Gold EEO certs online here. Just print them out to use.

Note that some of the coupons are single use (i.e. the B1G1 free dinner states that it can be used once). Others can be used multiple times (i.e. I printed out the B1G1 Free night and used each of them last weekend for two free nights in two different rooms.)
