What are the little green arrows on the furniture icons in the auctions?
I couldn't find any explanation to this... but what are those little green arrows? Do they indicate how much in demand an item is or its credit value or...?
they indicate that upgrades have been applied to the item. Each arrow is one upgrade.
they might be free upgrades, they might be credit upgrades, they might be subscriber only upgrades. Check carefully to make sure the price reflects the value of those upgrades.
