Sold out online at Tesco Direct so can't click and collect but still stock in some stores. I picked mine up at Bournemouth Extra branch where there were another 12 in stock apparently (I called to check stock in advance).
The price on the shelf hasn't been adjusted to show the reduction but it went through the till at £9.39 as advertised online. Couldn't find it cheaper elsewhere.
NB I also got Og on the Bog online at Tesco Direct last night under the same 1/3 off offer but I don't know if the price is cheaper elsewhere as I didn't check.
