Not too far off, $1AUD (0.60 euros) would be a cheap can of beans (which is often mostly water, even if it's a 400g can, once you drain the beans, your millage varies by brand) $3 a can is average for name brands that fill the can to the brim.
But when you can buy 500g of dried beans for $3.99, and that will make the equivalent of 8-10 cans of beans, as someone who doesn't eat meat (and has allergies so can't eat commercial "mock meats"), I eat at least 2 serves of legumes every single day. Buying cans adds up at that scale even though I'm just one person. So I always buy dry legumes when I can.
I definitely have some cans in the pantry for emergencies though, because they are very convenient.
But I also have some pre-cooked, unseasoned beans and chick peas in the freezer, when I cook up a big pot I always throw a few portions in the freezer. They defrost in less than a minute in the microwave, so I'll use them before I crack open a can of beans.
