luminary gold

Use the Featuring options appropriately. Setting all items to be featured/highlighted/bolded actually detracts from those truly special items that deserve the special luminary gold attention, and thus nullify this option completely.

Use images that focus on the item. Fancy armor and lots of background often make it difficult to actually see the item. Due to ongoing issues with the auction software, hosting your images offsite appears to be the best option if you wish your images to appear.

However, set your Buy Out price within reason. 20-50% above either the starting price or the reserve price based on the value of the item is a reasonable mark.

If using the Auto Relist feature, make sure you monitor your auctions carefully as duplication/deletion of auctions during this process has been reported.

Imagine the buyer's surprise if they contact you to trade for an item they believe they have won, only to find out you sold it to someone else because the software had duplicated your auction.

Also any item that has been relisted more than 5 times over a period of 30 days without selling is probably in need of a pricing adjustment.
