I'm here recently and did not fully understand how it works. Why do some escrow have 0% fees? Does this mean that they will not take money for their services? Thank you in advance.
Usually they are on low transactions. For example no one will keep 2 bitcoin without fee for a long time. To be fair it usually happens when escrower is new in this job but trustwortht or escrow isn't his/her job and does it when someone asks for.
But 0% fee doesn't includes transaction fee, you cut it from your money and that's fair.
And what didn't you understand? I'll try to help.
