Northern spices - bug?

This is pretty strange.

I keep trying to purchase northern spices but it fails and i get a "internal bag error".



First of all I've disabled all of my addons and still tried to purchase these with the same sad results.

I've also had 3 guildies try and they've had the same issue.



PS: I've also gone to the vendor in the Argent crusaders area, same result.


Should i report this as a bug, or is there some magic fix?!

I need to make my guilds fish feasts this week!
