I did preview, and I had shipping prices. But once posted, no prices would show up. My other shipping info showed up, just no price. It only affected items with my UPS profile (I have separate profiles for UPS, USPS Priority, and First Class). I've been using the same profile since I started using the site. I listed 2 items to be shipped UPS today, same problem, and I just revised them on eBay.
Another odd problem: I have been trying to list the same store item since Thursday, over and over. Each time it says it is posted, but it never comes up. I tried cutting and pasting the text into a new auction, with no success. I tried to make a new profile based on the last listing, again no success. I don't know what I'm doing wrong. I have listed multiple items since then with no issues. Any advice would be appreciated.
