Discount School Supply has a great code for 20% off everything through the end of the day today July 25. Just enter the code TWENTEV at checkout.
One of my favorite deals is on Magna-Tiles. This is an amazing toy and loved by kids 2-12. Every single child who comes to my home just loves these. They are pricey but well worth the money even when not on sale. With the discount code, the Magna-Tiles Classroom Value Pack 100 pieces is just $90.39. I know it seems expensive but these tiles are a bargain when you consider how much play they will get.
They are also some great deal on Legos. They have some of the best prices on basic sets that I have seen. Plus there are great deals on arts and crafts and more.
You will also get FREE DELIVERY on in-stock orders over $79 at Discount School Supply.
