So far there are three people willing to pay upwards of $400 for that Wonderedge, so it's not really a classical bidding war between to parties.
With that amount of pitting it's surprising that it's going that high, but at the end only those who are willing to pony up the dough know their reasoning.
I'm thinking if I really want one like that and haven't seen it show up in months and have the money, why not. We all value different things differently.
