Post your offers in fg, not ratios. This is how trade will be done for safety:
You send fg to my repay med, xJp, post a ss or copy/paste your gold log showing you send fg to him, and i had over the item. If i dont pay, and you can prove it, because i will be able to prove that i did, then just tell xJp and he will refund.
