i'm on a qtrly top up - they jsut top it up when they are passing.
means I never run out, but the guy came round last week - only 4-5 weeks after the previous visit and he put in 200 litres - which they then charged me 79p a litre for
now, i signed up to the qtrly top up in the expectation i'd get the best price (as they would just top me up when passing rather than arrange a special delivery) but i'm being fleeced, so I'm going to have to call and change the schedule unless they are more realistic with their charges/deliveries.
i find it amazing that the customers companies fleece the most are the ones that try to make things easy for them.
