I never saw avatar contact lenses in real shop. But i often saw avatar contact lenses at online. And most of them are very cheap. It is only need over 10$. I saw it at https://www.amazon.co.uk/Funky-Eyes-Avatar-Contact-Lenses/dp/B0039NSSS6, it prices as 13$ and also saw some in a online glasses shop https://www.eyesbright.com which signed with $ 15.99. Hope this helps.
