I do genuinely enjoy buying enough rice to last a year. Also bought a great cheap rice cooker at my local Chinese grocer. Idiot proof and almost certainly saves electricity.
I think I once worked out that the rice based meal I'd just eaten had cost less than a euro to make.
I'd love to buy in bulk like that, but I don't have the freezer space to treat the rice beforehand, so I usually don't buy more than 25 (just over 10 kilo) pounds at a time
