Hmm, well that UPS MyChoice is supposed to work where AS SOON as any shipment label has the address you signed up with, your supposed to get an immediate email notification. Then of course you will get more as the shipment is tracking along. If this is not how it works, then UPS MyChoice is a pretty useless tool, IMO.
I heard someone post that Googe <-> UPS has had some communication problems lately, but if UPS has the label/shipment, then that statement makes 0 sense.
Dunno... sounds like UPS is on the same Google "Notify Me" code... LMAO! (ie. never send an email!)
