I'm in the same situation.. but I think its because its being shipped as 'Freight' directly to the stores as opposed to individual shipments.
So its being shipped in individual boxes with our names but on 1 large pallet or in 1 large container with the others. I have a feeling I have the same 'tracking' as many other people. UPS does do Freight Deliveries as well.
+1.. when i enter my UPS tracking numbers it doesnt log any information either.. hopefully you are right.. id hate to find out some bad news on the day of.
