Quick advice: Growbag vs multi-pupose compost

[NotAnEMERGENCY]

I sent my OH out to get some multi-purpose compost because I need to pot on some perennials. He came back with a growbag (intended for tomatoes, peppers etc). Can I still use this or is it worth taking it back to the shop to exchange it?

it's fine.

That makes life easier! (And cheaper too: it was only £1.75 for 35 litres.)

I often use it. It just needs a bit of crumbling to make it finer!
It's really cheap in Autumn sell offs, I've bought some at rock bottom price to add to a new flower bed.

I'll keep an eye out for it in future too then...
