I checked Arm & Hammer web site for cat litter. It was so much crisper and more persuasive, and downloading coupons didn't require special software as for ODC. Both it and Cat's Pride are offering $1.00 off coupons.
It doesn't particularly bother me that ODC's site requires special software for a coupon - that may make it easier to prevent people from getting a coupon too frequently. My impression is that ODC is doing plenty of coupons through other methods for the new Cat's Pride Fresh & Light.
