At Toys "R" Us and Babies "R" Us retail locations, buy two Pampers value boxes of diapers and get $25 off. That's the best offer we've seen specifically for diapers at Toys and Babies "R" Us. (We've seen more general dollar-off coupons, but they're generally smaller discounts or require at least a $75 spend.) It's valid on packs of 88 or more and excludes bins. Deal ends July 20.
