You might all try Terapeak if you want to know what time and day of the week the most successful auctions end. I find my auctions have done much better since using this service. Who knew that 12 noon on Wednesday might be the very best time to sell a particular item.
Having said that, I am also extremely frustrated with Auctiva tonight. My auctions are in limbo somewhere out there and I am not sure what to do. I unscheduled them and posted to start at once to try to get into the best time for them to end, however, they are not showing up at eBay so I don't know where they are! Believe me, I am feeling everyone's pain.
