Saw this on another site. "I have a truckload of spare post holes I need to sell, approximately 1800 in all. These holes are 10" in diameter by 30" long and are made to fit an 8" post with sufficient room left for a tamping bar. Simply drop these in a hole 31" deep and 11" in diameter, insert an 8" post, fill & tamp, and you're done! Sacrifice for $2.50 each, or the whole truckload for $3000. Can ship via Priority Mail for $3.85, insurance extra. " What so you think? Is this a fair price?
