I bought 20 copies of my own book at the usual publisher 50% discount. This came to £100. I wrapped them up in old dressmaking pattern tissue paper (from my stash) and tied them with raffia, and then I posted them out to people I thought might be interested and also to people who might take a photo and put it on Instagram.
Sam, of the Empowered Author, was one of those people.
The postage and padded envelopes came to about £40.
Total spend £140.

I went to Clydebank, to the railway station called Singer (yes, there is a station named after the factory), to Fountainbridge Library in Edinburgh, to the Royal Infirmary and to the canal beside the former rubber factory where one of my characters fed the ducks at lunchtime.
