Last edited: Mar 20, 2017 at 10:33 PM Hi all! I am living in an apt. We have a bulk gas tank outside. Can anybody tell me how much does it cost to fill up a 1200 litres lpg bulk nowadays? My question is because i am charged by 5 euro per cubicmeter. And i think it's way more than anything. It is not a supplier price this is what the landlord tell me without any proof. I just wanna know how far is this from the truth.
