Laura Lee, are you sure they said they are getting rid of it all? or is it just the charcoal color?
Also Lesco too is being converted to John Deere, making it hard to get SMS from them or even Turface.
There is another option if you like the reddish coloration of the oil dri products. Special Kitty, kitty litter from Wal-Mart. I bought 25pounds for $2.75, thats actually the highest price I have heard of people paying for it. Even at that price though it is 1/10 cost of eco complete, fluorite, ADA, and 1/2 cost of SMS and profile roughly(in my local area). If you choose this kind, its the red bag, make sure it is the unscented type, with the only ingredient being ground clay. Better read up the post actually on kitty litter, it is lower on this page, seems I dont have the right one. Seems to be working though for me, testing it atm.
