Wouldn't recommend you trading with Towlie or any of them, Make sure to use an OMM. This isn't spam, But I'm pretty sure that ALL frequent Sythe users would know that GP for about $1.30/Mill is WAY overpriced, That's almost more than what gold4rs charges.
Bottom line: Make sure to use a TRUSTED Middleman or an Official middleman, Wouldn't hurt to pay 10M to make sure your trade goes the way you want it.
