Put some fuel in last Friday whilst we were out, tried to call at the Costco in Sheffield, but they were queued for over a 1/4 back up the road, gridlocking the whole place, so we managed to get past & put some in for £179.9 at a Shell garage. Had to go back out again today to Sheffield, we've done a far bit of mileage (for us anyway) this week so decided to call back round to see if the queues were as bad. Nowhere near & virtually drove straight onto a pump, £156.9, 23p per litre cheaper.
If Costco can sell what is supposed to be Premium diesel for £156.9 why are the others charging so much, pretty sure it's not a loss leader as most were filling up & driving away not going into the store.
