Consumer priority service mail allows green return card?

Does consumer priority service mail allow that green card that you can get like when you send things by certified mail? I need to send a package out and need to get that green card as well, but I try not to send by certified mail because it costs so much. It would be nice to be able to get that green return card with a cheaper shipping option.Consumer priority service mail allows green return card?
When you say consumer priority service mail, do you mean regular priority mail? I know the green card you're talking about and i think you can do it with any kind of shipping method. I believe it's a separate thing you have to pay for, so you should be able to do it regardless of your shipping method.
