Ordered a Gorillapod from USA, what will the customs charges be?

[JuliusSeizure]

I saw a kit going for R900 and so ordered it. I've ordered several items from Ebay over the years including an Android phone and never paid customs. They were all from China and maybe I was just lucky as the items were small and so the SAPO just let it pass, thinking it was inexpensive.

Does anyone have an idea what the fees will be like on a Gorillapod? I'm just hoping it's not too heavy.
