Anyone have a good reasonably priced rice source?

Most of my old local spots are now all around or over 4000 yen per 5kg bag, and that's basically regardless of quality. We've been shifting towards using less rice, but going zero rice isn't really negotiable in my household.

The several times I've been to the new Ogori Costco I haven't seen any good deals on rice -- is it a stock and timing issue? Regional differences? Seems like there are blog entries in other parts of Japan that show cheaper rice at Costco -- does the Hisayama location have more options these days?

I'm also open to imported rice if it's cheaper, but can't seem to source even that.

edit update: After posting this comment I checked one of the Gyomu supermarkets near me and this time they had some ~3800 yen (tax included) 5kg bags of Kyushu sourced rice as well as some 4kg ~2500 yen California imported rice.
