The theory was always “once you’re there, you’ll buy”. The reality appears to be quite different. Also, it’s a crapshoot for people anyway. I have (or had—not sure, because COVID) two LCSs—one in Cove and another in Reading. The former doesn’t do FCBD at all. The latter did, but when I asked if they'd get in the 2000 AD book last time there was one, I was told they’d ordered only one copy, and recommended I get there and queue very early in order to secure it. Parking in Reading is £4/hr. So I just waited until A Place in Space started selling them on its website for a quid, and used that outlet instead.
