I used a manual auger and one of those tweezers like scoop things. Treated 4"x 4" posts, post savers and postcrete to put 10 supports in for my deck (back edge is on a concrete pad, saving a further 5 supports). Also liberally treated the top of the posts. No mixer required. I reckon it will outlive my tenure in this house, more than enough for a shed.

more than enough for a shed.
Fwiw I was referring to TW garden room, which needs more supports Imo, that I'd probably want 100% confidence in the concrete mix. Whereas I think postcrete can vary.
I was actually going to say that for sheds it feels like post covid and all the garden room videos people tend to over engineer shed bases. People used to just put them on top of used council pavers.
I'm a big fan of ecobases from my limited use. You seem to need to do a similar amount of prep work whatever base you choose, but the application is super fast. Probably wouldn't do it for a full on garden room, but their weight limit is pretty high...

Good to know.
Given the overall costs I think it makes sense to get a mixer. On FBM they look to be £50-150, and you'd probably get most of the money back.
I guess it's just how easy they are to collect.
