Perhaps it's meant to make up for the lack of any fortified wine in the offer this time - something that only shows in very small print in store. In my local the ads were also well above head height. hopping in Sainsburys less and less now - and this puts us off even more.
You're right. They've just done an awful job of promoting its inclusion.
It's not a mistake.
I suspect this is a mistake to be honest. Get your orders in while you can.
Thanks, decent price for the Erdinger Weisbrau
