One thing i've noticed having just done my growbags, is that growbag compost seems to be much better than the multipurpose stuff, and it's actually a similar price, although there never seems to be multibuy offers on it. The original 33l levington growbags were 2.49, compared to most multi purposes at 60l at around 5-6 quid, although you usually get a 3rd free if buying two. But as has been said the quality of the multipurposes is generally terrible. I've tried JAB, New Horizon (which was ok but not half as good as last years), Verve, non of them were nice, all had plastic in, and lumps of wood.
The best compost i've bought this year was the new horizon vegetable compost for the raised veg beds, but again no deals on that. So it seems to me if you want decent stuff you're better off paying extra and getting veg products, as these seem to have less rubbish in (i wonder if there are rules about rubbish content for veg use??).
I think generally the only decent use of multipurpose now is mulch.
