Priority mail question?

[cuterlt]

Can you put a priority mail envelope (less than 13 oz) in a blue collection box, assuming it has all the correct postage and everything on it? The USPS website seems to say so, but I couldn't reach anyone at the info number.
Thanks!

Yes, you can. I do it all the time You can also put it in your mailbox as well, and the letter carrier will pick it up there (if it fits in the box of course!)
