Target has an amazing deal (happens every 3 months or so) on Purina Tidy Cats litter. Each 35lb tub of Instant Action, 24/7, and Glade litter is on sale for $11.99. If you buy 3+, there's a free $10 Target gift card offer. Additionally, in this week's ad, there's a coupon for $10 off a $40 pet purchase at Target, and in this week's coupons, $2 off an 8.5in or larger container of Tidy Cats litter (in store ONLY). So...buy 4x 35lb tubs (mix and match) for $47.96, minus the two coupons ($12) puts it at $35.96, and with the $10 Target gift card (so easy to spend on whatever that it's practically cash), that's only $25.96.
For those with Target credit cards, take another 5% off, making it either 140lbs for $24.66.
For comparison, the 35lb tubs are usually $12.99 each, with no sales, so the same amount would cost either $51.96, and Tidy Cats is a pretty decent quality litter brand.
Update: uminchu makes a great point...buying 3 @ 35lbs, and 1 @ 20lbs ($7) brings the cost/lb down to $0.17 (from $0.18 with my deal, and from $0.37 regularly), and the effective total (including gift card) to $20.97, so...go with that, if you like.
