Think that's older packaging, as it says Organix and not OGX, not that I'm an expert! In that case I'll look when I'm in the city tomorrow!
Is this not the same stuff?
I definitely have never seen it in mine (I'm lucky enough to have four city centre Poundlands within walking distance I visit quite regularly). Though, sometimes I just don't find things that others do, in other cities. Who knows! It's never been mentioned on the MSE Poundland thread and I've posted on there for years.
The OGX or the copy, Nutrafix?
