Informed mail wouldn't have helped me.
When Rv'ing I am not able to check mail everyday. And since I only had Sprint and storage bill sent to po box monthly. That would be 2 letters per month, I figured there wouldn't be a problem not picking it up regularly.
Well unknown to me the post office CLOSED my po box because Good Sam had over loaded it up 'daily' with all their junk mail. Add insult to injury I could not reopen my po box unless I went there in person.
Still think Good Sam should have had to pay for my expenses to travel 2,500 miles both ways to open my closed po box that THEIR copious junk mail caused.
