This addon, from Oribos Exchange, shows auction house pricing information in item tooltips. This addon will be updated multiple times each week.

• Commodity (stackable) items show the median lowest price of that item over the past 4 days in your region (US / EU / TW / KR).
• Non-stackable items show the median lowest prices of that item over the past 4 days in your realm and in your region.
• Equippable items from the current expansion will show prices specific to each item level and variation ("of the Fireflash", "of the Quickblade").
• Caged battle pets also show pricing information, with prices specific to each breed.

Use /oetooltip to view/change settings.
