Is there any way to change the date on the mailing label?  For example, I'd like to purchase printable postage today so I can wrap the books, but I will not be going to the PO until Thursday so I would like the date on the label to be Sept 20 2007.  Thanks in advance.

Elizabeth, that question came up when the printable postage first went into effect. If I remember correctly, no - you cannot change the date. But your label is good for 72 hours according to R&R's answer.

Uh oh! R&R told us 72 hours. I'm not mailing mine the day I print them but so far the first two have gotten there fine. The one today was not printed today,  really hope there is no issues. I'm already doubting I'll use PBS postage with the fees in the kiosk and the DC not being scanned for quick credit, not even when it's delivered. Having a book returned after I pay will really push my button.
