Here are the 12 printable coupons good for Sunday only. Thanks goes to Lisa for the link to the coupons.
My favorite coupon is for “Buy 1 Get 2 Free” for Knot Wood Foam items (assortment varies). Depending on what 3 items you buy, you could save up to 66% on the regular price. I found this Shape Sorter on the Toys ‘R Us website. I have no idea if they sell this toy in their stores or what the in-store selection is priced at, but you might want to check it out if you are shopping at Toys ‘R Us on Sunday.
