I went thru the exercise of selling a domain at Pool.
It was sold three times. And, apparently, the third buyer must be going thru with payment.
However, Pool holds the money for 75 days to make sure the charge goes thru.
Even though, I sold it for a nice profit. And, a have over 60 names at NameScout.
I have no plans to use them again. Unless, they totally change the whole process.
