Most expensive item you've ever sold/bought?

[Garfalon]

I recently got a personal best of 3500g for selling an item (see if you can guess what). I think the most I've spent on something (excluding the epic flying mount skill) is 1200g.

Can anyone beat my 3500g record?

Not I, the highest I got was 2k for an item. A nice Welp pet.

And mine was 3100g. Can you guess?
