Mail box eccetera

You're referring to the phrase "mail box, etc."!

In this context, "etc." is an abbreviation for the Latin phrase "et cetera," which means "and the rest" or "and so on." It's often used to indicate that there are additional items or details that are not listed or specified, but are implied or understood.

In the case of "mail box, etc.," it's likely being used to suggest that there are other items or services related to mailboxes that are not being explicitly mentioned, but are still part of the overall concept or category.

For example, you might see "mail box, etc." listed on a menu or in a catalog, followed by a list of specific items or services related to mailboxes, such as mailbox rentals, mailbox installation, mailbox maintenance, etc.

So, in short, "mail box, etc." is a shorthand way of saying "mailboxes and all the related stuff"!
