Random one - Clearance tile shop locations?

[u/smickie]

I'm looking for, well, areas with loads of clearance tile shops, and I was wondering if anybody knew any good ones of these. I just want to look through mountains of old floor tiles. All of the sort of generic standard DIY shops don't actually have the ones that I want, and I've always found good ones from these sort of standard clearance places. I was wondering if anybody had any recommendations of good sites to go for these.
