Last summer I had an idea. As well as writing up my trip walking Wainwright's Coast to Coast walk, why not make a downloadable version available as well, sold for Amazon Kindle? Today, the first royalty cheque arrived.
Turns out that in the end, the £8 had never been refunded to the credit card in the first place - they'd refunded it as a gift certificate instead, mainly as the original purchase had been mostly gift certificate based.
