There are some awesome $3/1 Huggies coupons out there right now. Go to the link here to print of your coupons (print 2 per computer). These were just added yesterday, but I'm guessing their print limit will be reached soon, so I would recommend printing these off soon.
You can also become a fan of Huggies on facebook and get access to print another 2 coupons for $3/1 pack of Huggies.
From what I hear there may be a good diaper deal with Huggies at Walgreens this coming week that these coupons would go great with. I'll update you on this when I find out more.
update: There is a deal this week at Walgreens--buy 3 packs of Huggies diapers at $8.99 each, get $5RR. Use 3 of your $3/1 coupons plus the $1/1 WAGS coupon from the Children's Activity Book put out last fall if you still have it to get your total out of pocket down to $14.97. If you factor in the $5 RR you earn, you have spent essentially $3.32 per pack of diapers.
There is also another link for another $3/1 Huggies coupon (I know--can you believe all these awesome coupons they are putting out right now?!) Go here to print your 2 coupons per computer.
