More words can be purchased using either money or credits: £1.50 for 500 posted words or 3 credits for 1000 words sent as a PDF, up to a limit of 6,000 words (£18.00 or 18 credits) per prompt.

I may have asked this before and forgotten the answer but I would prefer to use credits (languishing unused) to purchase posted words. Is that possible? I cannot afford £ but do not want to selfishly deprive your other readers of your words.
