The Many Writings of K. A. Jones

a copy of an unsponsored story emailed to you, between 6000 and 10,000 words, for your eyes only

This means a story that has already been written and is on the unsponsored stories list, which is why it specifically says unsponsored.

one story of at least 1000 words written, unposted, which may be a continuation of any story (including character adoption, named character and named setting stories), a new story for any character, a past or future story for any collection, a crossover, or an AU

This is a new story, so if you were buying during a time that isn't a prompts session then each of your prompts would be charged at 3 credits per 1000 words of story. During a prompts session you will get 500 words free for any prompt and then continuations are 3 credits per 1000 unposted words (or £3 if you want them posted). Your continuation is for someone else's prompt so the 500 free words have already been posted and you have bought another 1000 words, which will be sent to you in a PDF so I can put it up for sponsorship after the prompts session has finished.
