Gah! I went to Home Depot with SKU# in hand, and went back to the lumber area with great anticipation. I found the tag with the correct SKU#, and proceeded to look through the stack.
Something didn't look right. The boards seemed a bit small. I found the UPC label and realized the boards in the stack with the Do-Able SKU# weren't the right ones. I looked above and below, but the correct boards were nowhere to be found. I was about to find a helpful associate, but upon investigating the other stacks in the vicinity, noticed than NO SINGLE ITEM was in the proper place marked with the proper price.
I won't be going back to that particular Home Depot.
The search continues...
