I can't guarantee all 16pks are inferior, but I can guarantee the 16pk I had was definitely different to the 9pks as I always buy this brand. When I figured there was a difference I bought a 9pk from same store for £3.75 & compared then.......Sod me, I need to get a life lol, but it's a true story!

£5 at co-op or £4.50 with student discount

Cheaper than prime :man:

Managed to get 40 for £10.62 (equilivent to £4.25 for 16) last week with Amazon 15% subscribed/save.

Price gone back up now.

They're only £5 at Tesco anyway - at least they were on Thursday.

​offer must have finished at the weekend then

They are/were supposed to be on offer for £5 since 25th Jan until 14th Feb. They're currently showing as unavailable online so not sure if it ended early or not. Screenshot posted here showing the dates.

Ok, I don't want to come across like a poo roll snob but the rolls in the 16pk are inferior quality to the ones is the 9pk, presumably made in different place as the pattern is also different.
They are up to the job, but it's a bit cheeky of Kleenex.
Not voting, just wanted to warn fellow hukders who wanted the good toilet pepper
