First of all, I love shopping at Wayfair.com.  They have not only amazing selection of gray products, but also the lowest price with free super fast shipping.  Their customer service is top rated and they make sure you are happy with your purchase.  Sandbox arrived within a few days. I went to home depot to pick up play sands. Instruction says you can put up to 30 lbs, but I recommend 15 20lbs. A lid is nicely fit so that no bugs come in. Its also large enough for 2 kids.
