I have a few X99 SLi cards from reputable dealers here in Stockholm that I could get for you, brand new and the usual warranty worldwide from Gigabyte. it would be around 320 USD incl shipping which insured is around 35-40 dollars in todays exchange rate.
Let me know if you can't find what you want and i will ship one to you asap. Takes 3-5 biz days according to UPS and DHL.
I will gladly help you out so let me know what you need
