They aren't (yet) closing many Argos stores in the UK. All their stores in Republic of Ireland have closed, but only 7 are listed for closure on the mainland, 1 in Scotland, 4 in England, 2 in Wales. All bar the Welsh ones have already closed, and the two Welsh ones go this month.
But that still leaves around 800 stand alone Argos stores currently - which is expected to fall to something like 160 by the end of 2024. I can[t find any list of which stores will be closing after this month, or of which are expected to be the 160 kept open.
I still have three within a 20 minute cycle, though I imagine at least one of those will be going when the new Sainburys superstore opens in Pontyclun next spring, as it is less than a mile from the Talbot Green one.
