You get junk mail because you look forward to it and you'll read it. Wait until you find out how long you actually keep it in your house before you throw it out.
There are ways you can prepare your mailbox for a Michigan winter but if a snowplow damages it, your reimbursement isn't based on IF a plow did it, but HOW.
The cops would love to talk to you if your mailbox was a victim in Williamston. Please call them, come see them, and bring the receipts. Someone's headed to jail and going to have to pay for a lot of mailboxes.
