Toys R Us has a few discount codes that are stacking!
25% off - CS25
20% off - CS20
15% off - CS15
When combined you are getting 49% off your purchase.
This is working on toys and video games.
Also, if you are buying baby stuff, you can also stack with Turkey25
I recommend doing in store pick up if possible
Good luck all.
It looks like it works once per account.
Note, if you are using a gift card to pay, put the gift cards in before you enter these promo codes.
