I got reduced compost from morrisons last November . was £3 for 40l ? of new horizon, so I bought quite a few bags, and i also picked up some of their 70l bales of coir for £2.50 each. I'll need to add compost, fertilizer and perlite or vermiculite to that to make it useable but its a good price for it and is a good replacement for peat based composts
The allotment forum here sells sylvagrow 40l for £12.50 which is just too much for me.
Covid era peat free really was the worst, but I think it got a bit better last year, I had bowers, Jack's magic and new horizon last year and it was all useable. The premium stuff like sylvagrow and dalefoot is very good when I've bought them in the past.
