This one is gone now.
There is a new $2/1 Seventh Generation coupon that is good on baby products like diapers, wipes or training pants. You can probably use this coupon to get a tub of wipes for at least 66% off. I have seen them on sale for $3 each and I think they are a bit over $3 at Babies R Us.
Thanks, Coupon Geek!
