I use a new website called ebates.com it pays you back for many purchases made on the Internet,
When you order online at home depot you get back 5% at lowes you get back 6% also at lowes it said 2 bag maximum on their sales flyer but online line I just tried to order 10 bags no problem, I get around 200-300 cash back from purchases from ebates, when you order online you go to customer service desk and the charcoal is waiting on a cart for you it's great
Also use promo code MEMHD5 to get 5 off 50 at home depot plus money back from ebates
I promise this thing works
