I sell stuff in AH by this method: I set a high bid = buyout for an item. After some hours/half a day I cancel any of the remaining auctions, and then post them again with half the bid and buyout. And so and so. Eventually an item will either sell or reach bellow 100k, at that point I prefer to vendor it.
As you know many people are reporting serious AH lag and issues in the last two weeks. What I find it strange is that most of the items I post and cancel and post do not have LAG issues. But a small percentage of the items I put in AH always have issues. I started annotating their names. Whenever I cancel some boots, I can expect the cancel procedure to take long before the item is added to the finished tab. Then the same item will take a long time to be sent back to the stash. Finally, putting the item up in the AH will take very long. Actually, they appear in the auction list with a label that says "authorizing", bid and buyout are not visible for a while.
Lately, I first cancel all the items. Then post only the items that didn't take too long to cancel first. None of those items have any delay when moving to the stash and when getting added back to the AH. Then I go back to the (currently 3) bugged items, and as predicted, issues and issues and long waits.
Could it be that some items are getting flagged for some reason?
