First, you can message me about the price to get a 2% discount on the item, as I would usually tack that on for you to pay.
If the item is of equal value and NOT OVERLY INFLATED, then you may get me to consider a trade. And don't think you'd be clever by trying to pull that on me. It's why Gaia lists the Average buy price.
Anyone trying to hack me, or scam me, will be reported. I will then laugh at your expense instead of you laughing at mine.
Lastly, don't try to be all "buddy buddy" with me to see if you can get an even better deal on the items I have for sale. It won't work and I hate it when people try that s**t on me.
