I'm so (minorly) annoyed right now

The Herald of Tzeentch I got off a friend a while ago is actually missing its tail, and the leftover sprues he gave me don't have it on there. Normally that would mean just buying the extra part off a 3rd party website, but apparently you can only buy the entire bloody herald!

I'm not paying 17 whole British Pounds for that, plus another 5.5 Pounds for international shipping!
