Tomorrow (1/6) Toys Are Us will have jumbo packs of Earths Best diapers on sale for just $5 with this coupon. Take this coupon along too (click here) and you should be able to get them for just $3.50. Please note not all Toys R Us branches will honor a manufacturers coupon with a Toys R Us coupon on the same item so please use the $5 one first and hope for the best!
To use the Toys R Us coupon you must be a member. You can sign up in store before you check out. If you are already a member check your email and spam box as I received these coupons with two $5 off ones for the money I spent with them in December.
this post I wrote earlier in the week telling you how you can get them for 40% off.
