My local indie bookshop does me a discount (partly because I brute-forced him into setting up his business account, long story) so I order all my fiction there.
Business books all come off Ebay.
I'm seeing the bookshop guy this afternoon for "Last F2F Buy Before Lockdown" and I'll ask him about this.
He said "registering myself now, it's still better for the bookshop if you buy direct from them"
