Searching Sales By [character] Filtered On [item].

I was trying to find out how much of a specific item I sold through the auction house. The issue I ran into is that I've been selling that specific item sporadicly since over a year ago and I can't look that far back in my own FFXIAH history. A nice feature would be the ability to choose a certain item and a character and have FFXIAH return a result set containing when said item was sold by that character much like when you browse a characters FFXIAH history (but instead filtered). Maybe give the players the option to let only themselves and/or their friends and/or the general public be able to make such a query.

Why would you want to look up prices more than a year ago? Just add 50k to the current value of the item? :P But serious question.

"You don't need a paypal account to donate, all major credit cards accepted. Use the Paypal button on the right to donate. Our current hosting expense is $820/month."

This is the reason logs aren't kept that far back, I assume.

well, i don't have much to contribute to you other than a possible alternative (although i doubt it will work for a year ago...) i set my profile to show 255 items, which for me goes back to January at the moment. then when you expand your sale history, hit CTRL F to find the item you're looking for.
