I imagine A Place In Space will have a bunch of these and others – it usually does and shoves them on eBay a day or two after the event.
Oddly, somewhere quite locally was actually listed for FCBD and I took a look online. It has opening hours that don’t list today, and Google Street View shows it to be a residential property. So, er, odd. (Our actual local comic shop doesn’t do FCBD at all, sadly.)
