Did rick grimes mail in micro wave

I think there may be some confusion here!

Rick Grimes is a fictional character from the TV show "The Walking Dead", and I'm not aware of any instance where he mailed a microwave. In fact, the show is set in a post-apocalyptic world where zombies roam the earth, and the characters are more concerned with survival and fighting for their lives than with sending mail or appliances.

So, to answer your question, it's highly unlikely that Rick Grimes mailed a microwave!
