When we have to buy gravel or soil, the most economical way is for us to drive to the builders' yard in Yzeures. Gravel and topsoil isn't expensive, but having it delivered is. It's a simple procedure, but one for which you need a trailer.
You drive into the yard and wait until the weighbridge (bascule) is vacant. Once there you go to the office, tell the person behind the counter what you're after, and she weighs your vehicle and gives you a ticket. She then directs you to whatever part of the yard the desired materiel is stored and you wait for the man in the digger to arrive.
