I've just bought a soap offcuts box from Friendly Soap (EBay).
Looking back through this thread - they've more than doubled in price since last time I bought some (2021) . Now £16.95 for 1.25 grammes (incl P&P) - were £7 for a box + P&P.  
However, I haven't bought any soap since my previous purchase of 4kgs., though I have collected some FREE soap meanwhile. Should complain really!

I bought some at a similar time (don't think it was 4Kg though?) and ran out a while ago. I won't be buying any mroe though as I bought a job lot of Imperial Leather which I really like.

My July 2022 purchase of a 1.9kg box of soap from eBay is nearly finished. £15.75 I paid (including P&P). She doesn't sell soap anymore though, unfortunately. A similar weight of offcuts would cost me ~£40 now. eBay seems to be flooded with soap sellers, and there are multiple accounts selling the exact same product.
