I've learned that if something gets lost in postal zone you could still get it- months later! One of dh's direct deposit pay stubs for a company he no longer worked for showed up in our box almost 8 months after the post marked date. It looked like coffee had been spilled on it, dried out and also had mold all over it. My post office said that was how they got it in their office that morning and that there was no way it could have gotten dropped in the floor of the mail car and kicked under a seat because 'they thoroughly check each car every day.' Nothing they could do about condition of it. I do hope you get the other blocks soon and hopefully NOT in the condition our postal zone mishap returned our lost mail.
