I have my oil delivered on a planned basis and pay monthly by direct debit. This week their usual email arrived letting me know that a delivery is due and giving me the price per litre.
OH did a big of digging around and found I could get the oil much cheaper elsewhere.
Now to be honest I am fairly lazy where this sort of thing is concerned and tend to always stick with the same company. However, this morning I rang the original company and told them I could get it 8p per litre cheaper elsewhere which is a substantial sum when you are ordering 1500 litres.
Anyway, after asking who the cheaper oil was with, without any haggling, they agreed to delivery the oil at the same cost. Yipee.....
