Cheap Drunk: CO-OP's Suntory Rich Malt?

I have been liking Suntory's Rich Malt quite a lot lately, and while they have seasonal special brews, their standard one is just as good.

With that said, I saw this standard Rich Malt at a CO-OP supermarket, and that I found interesting is that they have the CO-OP name printed onto the can itself on the side.

The drink itself is nothing different at all, so I am not sure what kind of "collaboration" this is. I imagine that CO-OP's delivery services will push Rich Malt over other happoshu.
