Although I couldn't find exactly what I wanted, they checked every other source nearby for me. Evidently there's been a run on tan border blocks. Got what I needed at a great price. Loaded me up quickly. Happy.
Very helpful and knowledgeable staff. They recommended all the product and tools needed to complete my small cultured stone project!
