Made in the same factory?

I was chatting to a friend at the weekend about things having diifferent names but being from the same factory such as,

Levingtons compost being the same as Focus and big diy store ones.

do any of you guys pick up the same stuff but labelled differently?.

D ont risk getting in to troubleover it but if you can divulge im sure many of us would be interested.

used to work for British Bakeries who made bread for M & S,Tesco,Sainsbury,Co-op,Budgens and many others

Quite a fwe English mustards for major stores are made in Colman’s plant in Norwich.
And tesco’s, Sainsbury’s and M&S’s handcooked crisps are made by kettle Chips in Norwich too (just using slilghtly cheaper spuds)
