Sainsbury's long-life soya milk question

My husband and I used to buy the long-life soya which was 89p. Last two weeks, Sainsburys has been completely wiped out by Saturday mid-morning which is not normal. We've had to start buying the more expensive soya milks again.

Either there are lots more vegans in my local area (yay) or, are Sainsburys are potentially going to discontinue the long-life soya? I don't know.

Anyone found the same issue?

**Update: It's back! The rebranding is all completed and we got our normal soya milk yesterday. Yay!**
