cq, I don't think it is a matter of giving wrong information, this feature appears to be randomly applied.  For example, I ended all my listings early December whle I was away on holidays, bulk relisted just before Xmas when I returned (thinking they would all get the 3 free relists) and found myself stuck just yesterday when they all ended up in unsold.  Did a similar thing in October and the relists worked, so you just can't tell.  Best to d a random check, as you say, but you don't need to open each listing to check, you cn do it much quicker in MySelling.  Just click the drop down menu at the right o each listing and see if the last option says Remove Automatic Relisting.  If it doesn't then it isn't set.
