WoW /data/wow/item API returns incorrect purchase_price

See this post: Not possible to get reputation and cost required to get a WoW mount?

If you attempt to get the item info for item 161667, which is “Reins of the Voldunai Dunescraper,” you get a purchase_price with a value of 1.

This item actually costs 90000 gold.

This is the API call:<YOUR TOKEN>

I have not tested other mount items, but it’s reasonable to assume other mounts have the same issue.
