John West Tuna chunks in brine.
6 tins for £2.79 seems a pretty good deal. The packaging says 3 + 3 free.
Sorry if already posted. Did do a search and couldn't see it.
It wasn't stacked with the rest of the Tuna, it had its own space elsewhere in the store so might have to search or ask.
Also it was in a Scottish store, just in case it's regional.
