Well the highest bid before the $30,000 was $140. Yes that's right the bidding jumped from $140 to $30,000. (I want to clarify the $30,000 was the buy it now) This is very strange and makes most think there is an error somewhere.
You can look at the bidding here
I hope the owner made one heck of a sale and congrats, I am not saying the sale did not happen,I think Flippa needs to make sure these odd sales are explained and assures those using Flippa and the larger domaining community as a whole that these sales are legit.
