You should be able to get your UPS tracking info however the tracking code doesn't resolve. Since its Sunday I would anticipate the UPS tracking code to work late tonight or sometime monday.
I forget when UPS updates their tracking information on items ready for pickup but I think its a good sign if you have a UPS tracking code that doesn't resolve yet on UPS site.
I remember when Onsale was an auction site. They did really good until packing got extremely poor or really missing on items shipped. Looks like they are making some sort of a comeback though.
