I recently had a book requested from me with the RC asking that I use DC bc the recipient has a problem carrier.  Now, I have absolutely no problem w/ this - especially since I already use DC.  But I was wondering, would DC actually assure that the carrier would deliver the package? Or are they asking for the DC for my sake - so I get my credit no matter what? 

I just started wondering and I can't stop wondering till I have some answers... I'm an extremely curious person.  Hmmm...maybe I should PM and ask....  Anyway, any ideas?

Not really. All DC does is ensure that the book is delivered "somewhere". It isn't going to necessarily be her house - especially if she is having carrier issues. This is rare, however. I think she may be looking for proof that her carrier is messing up by being able to show the PO that DC say the book was delivered in case it isn't.

I hadn't thought of that.  I knew DC isn't a guarantee against lost books - I actually have a BoB box that I was supposed to have received and apprears to have gone to Minnesota (I'm in Indiana) - but I thought maybe the DC was intended to "scare" the carrier into delivering it.  Then again, if it can be used as proof, maybe it will.

I've had problems with my last few orders.  R&R think that my local PO isn't uploading information b/c they have no record of my DC.  I am going to talk to my local postmaster on Monday to see what the deal is.  I do the printable postage 'cause it's easy as heck and I can just drop most books in the blue box across the street and find out when they are delivered.

I know if I put DC on a package, it gets delivered 100% of the time.  They may have observed the same phenomenon.

You could PM the requestor and ask....

I have also noticed that things with DC get delivered for me. Only things without DC have gone lost.
