CPA, Thank you for our lightweight top soil which we are very happy with. Our only gripe is that we had no idea when it was to be delivered, except we hoped it would appear on the date we specified. It would have been nice to have the delivery date confirmed by the transporters, and even an approximate time of day, but we were glad to get it when it did come and we did stay in all day to receive it. Thank you. Tony
