Way too many mistakes happening here! Our mail is frequently delivered to neighbors homes and we get miss- delivered mail from addresses that aren't anywhere near us. Our most recent mishap was receiving three identical sets of the clipper magazine with inserts for grocery stores. I surely don't need three, however I think the other two neighbors that didn't get them may have liked to receive theirs. Just two days ago I put a miss-delivered piece of mail back in my box with the flag up so the carrier could correct the mistake, but they only put the flag down, left the mail I put in and placed my new mail on top of it. I don't know if these complaints get any attention, but let's hope for some improvement.


Package was delivered today (4/7/2017). Package too big to fit in box plus box was full due to accumulated mail delivery today. Delivery person LAID PACKAGE ON TOP OF MAIL BOX! I watched thru the front door. It is windy, raining and snowing. No way it would stay balanced on top of box. Why not place package on front porch or against garage or mud room door?
