I have several concrete blocks I purchased from Home Depot last year and now decided not to use them as planned. They are $3.21 per block at Home Depot. I am selling for more than half off at $1.50 per block. I can not ship or deliver them. I can help you load by hand. Here is Home Depot's description below.

16 in. x 8 in. x 4 in Concrete Block 33 lb. is manufactured to ASTM C 90 specifications and used in foundations and above-grade masonry walls. This heavy weight solid block is uniformly square and free of large chips. These heavy weight interlocking gray blocks are uniform in texture, size and color while being dimensional and accurate.
