We were able to pick up a 25# bag at our local feed store...I think it was about $12 or so. I looked online too, and the issue with getting stuff that weighs so much is always the shipping :( Seems it often costs more than the product! Sheesh.
What a great idea!! That'll make cleaning sooooo much easier! Don't think we can do it on ours but I'll mention it to hubby as ours is still in construction phase.
