You can't buy them individually as a sole purchaser but sfs can do them as a group buy.......there is another group buy in the 600 section which i think was struggling to get the required numbers, i think 10.
I had a quick search for it but couldnt see it but if you spend enough time going through the history on the 600 section you should be able to find it....i think it had comments within the last 2 months so you shouldnt need to go back too many pages......they might be glad to have you as another purchaser.
