Home Depot had an ad in the paper for blue bag for: 2-20 lb. bags for $9.97. When I got to the store it was marked $7.97. I bought 3 of the 2-packs, and thought it must be a misprint on the sign that was in front of the bags. When I got to the register it scanned as $7.97. That's $8 for 40 lbs. It also says as long as supply lasts. The lady said this sale was at all H.D. stores. I should have bought the whole pallet.
