I can only give my experience with them and it was NOT good. I ordered some items online and had them sent via Priority Mail to them. They show that they received them BUT I never got them. Over $250 worth of items. Then I was sent some checks that also did not get through their system to me. During this period I received W-2's for two other mail box users that I returned to AMB. I asked them if they did any internal auditing and the answer was - "we never have any problems so it doesn't pay". I stopped using them the next week and switched to My Dakota Address which does do internal auditing - no problems since. You may never have a problem but if you do you might want someone who can tell you what went on.
