Why bid before making sure of the details? 
I was sure of the details. In the Auctions - Guidelines and Tips! it is clearly stated:
...
Use a trusted escrow or middleman to protect both parties!
...
...
Everyone: Exercise caution when trading with strangers, and always use an escrow when in doubt.
...
I admit it's not a rule but it's a guide and I was preety shure that if we are in auctions we both respect it and if not it's your responsability to state all your terms, especially that you don't accept escrow. I have done many trades in here and escrow was by default but you are right also, I should have asked first.
