I am terrible at pricing myself. I always price too low and my wife says I give my stuff away too cheap.
Depending on what your going to include with this set(I seem to remember a pair of vambraces for some reason). The breastplate alone with the pauldrons and the tassets as pictured is worth at least $950 US minimum.
I have the same problem with low prices , my friend! Moreover, in our country not many people can pay an adequate money. So I plan to enter the international market But I don't know the needs of European and American consumers. As I understand it, few people need heavy armor for the full-contact. Most are interested in nice stylish image and shape.
