Try searching on ebay, they sometimes have them on there. I saw an Ogakor buff on there once. Mind you, it was around $200. The only other place I know to try is the CBS website.

This was my second thought (after googling "Survivor Merch"), and I only found one Hae Da Fung buff, and it was signed by a lot of Survivor China contestants and costed well over 200 bucks.
