Makes me wonder if they didn't try to "cheat" the system by establishing two accounts using different addresses, since you can only have one account per address.  Are the account names/nicknames for both orders the same?  If so, then I'd consider just mailing them together and use the address for whichever was the second order. 

There's no way to cheat the system it goes by IP address which is attatched to the house/phone line and not the house/street number. It's why people in dorms and apartment buildings and library computer users have had problems.  They don't get the free credits sometimes even though no one in their immediate household has an account but because the IP address is tied to the phone line going from the street into the building-or something like that. 

If the whole name and city is the same then I'd just pick one to mail to-the 2nd order seems like the best choice.  Maybe use the PBS DC on this one.  Have you tried reprinting the address to see if they both match now? 

If the orders weren't made at exactly the same time (maybe a few hours or something apart)-it's possible that they went out and got (or cancelled) a PO box and then changed it before making the 2nd order. 

Another thing: Always choose the 5 day mail option even if you plan to mail that same day. You just never know what might come up and you'll need those extra days.  There's no penalty for mailing early but that 5 day option gives you a cushion against life unexpectedly getting in the way.  I choose the 5 day option even when book orders come in while I'm printing labels and wrapping books. 

You can choose to send a book to a friend, so maybe the friend is themself at a different address.  Somebody took time to post the second address.

Perhaps this person has a reason for not wanting one book to arrive at the "address".  If it were me, and I didn't hear from them, I think I'd send them seperately.  Just a thought.....

I would send them to the addresses provided unless you hear back from them. It'd be nice to save on postage, but the orders show that you should ship to separate addresses so thats what I think you'd need to do unless the requester agrees to doing otherwise.

I'd send them seperately, which is a bummer.  My best guess is along the lines of what Cynthia said.  Maybe one book is meant to be a gift for a person in the house so they're having it sent to the PO box.  Although why they wouldn't just have both sent to the PO box then?  How common is the name (is it the same nickname?)  I suppose in a one in a million chance you could get orders from two Mary Smith's that live in the same city.  I'd say that is a reeeeeeaaaaaaalllllllly long shot though.  LOL

I hope you hear from them soon so maybe you can save on postage. 

Actually PBS allows two accounts per address/IP, each must be registered to a different adult ie spouse, MIL, adult child, etc.  And two seperate accounts would probably show up differently on Christopher's request tab.

Unless you are mailing weeks late, or have other major member issues, the mail dates are not enforced by TPTB.  Another day or two isn't going to cause you to receive a reprimand.  Unfortunately, I can think of several legit scenarios to the seperate address.

I first went to print off the labels yesterday morning (planning on mailing them yesterday), and saw that the addresses were different. So I sent a PM. When I didn't hear back by late yesterday afternoon, I printed out the labels (still showing different addresses) so that I would have a printed copy of which ever one I needed to use if I heard back this weekend. But since I still haven't heard back, I guess I'll wait until Monday, and if there's still no response at that time, I'll go ahead and mail the books in separate wrappers.

I'm still unsure how the two different addresses happened. They were ordered within a couple hours of each other late Thursday evening, so it seems unlikely that the other member suddenly decided to start or stop using a post office box. But the "information for the receiver" text on each printout says "please log in to your account" (emphasis mine), while I believe that when shipping to an alternate address the "information for receiver" says something about your friend requesting this book for you, and you should let them know you got it. So I'm utterly confused. I'm sort of hoping to get a response, for no other reason than to maybe find out why/how two different addresses showed up for the same account.

I would have to think the requestor did it on purpose. And, you can never get in trouble for following the mailing instructions that you were given through the system. So, if you don't hear back, you should mail them separately.

Otherwise, the requestor could have a legitimate complaint against you, if he requested it that way on purpose and you disregarded it. 

But, also, it doesn't hurt to request clarification via PM, since you noticed the difference. Definitely do it the way it was requested, though, if he doesn't answer.

And, I don't think you should wait for a response past the day you said you would mail it out. Give him till the end of Monday, if that is your mailing out day, and mail them out Tues morning if you don't hear back.

And, he could be mailing to a friend. Maybe he himself uses a PO for his own mail, and is sending the other book to his friend at the address. Unless the zip is the same too, it could be quite a trek across the city to those 2 different addresses.
