I had to order my Sylvagrow on-line as I don't drive now so got two 50 L for £30. Ok, not cheap but looks good (see attached close up pic with flash on of a trowel-full spread out on a piece of white paper on my posh shed bench). It was what I'd call nicely dampish, and any "clods" around the sides of the bag were easily removed then broken down with my fingers.
p.s. I used to like Jack's Magic, but maybe it was either 2021 year's stock and/ or a storage issue with a small local nursery but it was rather wet with a white mould on top.
