They lie and wont provide all the information as to what the total cost is to the seller. Why have a hidden fee?
It is inexcusable for all their agents to "forget" about a $1500 fee + tax that they will charge you if you get a lock box service from them... this is of course on top of the $399+ tax that they say is the only cost for the service.
As a buyer I was lied to when I bought through them and never got the money I was promised (at the time comfree quickly changed their website, so I didn't have the proof from their website to show them).
I highly recommend against a company that cannot keep its word or lies to get your business.
