thanks for the responses, AndyTiedye, Telkin, and Bob_G.
I guess if people who tried to get in on the sale within a few minutes of the original post but didn't succeed got disappointed, it's kind of funny I come to it 2 days later and am surprised that it is still not going on! LOL
I also hadn't realized that people can edit their posts after they post them - it makes sense, I guess, that they can do this, so new readers don't react to outdated info; on the other hand, it can also be misleading in its own way (as I didn't understand what happened until you explained it to me).
OK, so now I understand a bit better how the whole thing works, not that it helps very much in a practical way, as even if I decided that I really wanted one the chances are very, very small that I might succeed in getting one in the original sale.
Probably better that way, anyway,
