Check out this find by Julia at the Frugal Find. Target sells the 10lb bags of Tidy Cat litter for $1.77. Use the $1/1 Tidy Cat litter printable coupon to pay only 77 cents for it. At Target you can also use the $1/1 Friskies Party mix cat treat coupon to pay less than 50 cents for a bag.
Do you know the price of this cat litter at other stores. I would think that it is probably just as cheap at Walmart if they carry the product. Catch up with all Target deals here.
