Always use your calculator when buying these products; what looks like a great deal can often be misleading.
Perki, that compost works out at £5.97 for 105 litres. (5.68p per litre) That is not a bad price, but other places are doing offers on 3x70litres for £10, (4.76p per l) which is cheaper.
As to quality, I have seen everyone's comments about growing medium quality over the last 2 years and it really seems to be a game of chance.
Always try to make your own compost and eke it out by adding some sharp sand and these commercial 'growing mediums' (they are not really compost)
