It is the 28th October and I can go and buy The Little Friend! Happy Birthday Me!
I don't think my one man protest will have made much difference. At least the embargo-breaking seems to have been universal, so no-one will have gained extra market share- which means that breaking it has achieved very little. You could also question the wisdom of publishing a big novel at the end of October, when budget-chasing retailers are pretty unlikely to leave it sitting in the stock cupboard because a publisher tells them to.
