I found some pretty steeply marked down toys and games on Amazon; everything here should get there in time with free Prime/SuperSaver shipping.
Spirograph Shapes Set, $10.00 with free Prime/SuperSaver shipping (pictured at the top of this post).
Matchbox Dumpin' Loader Vehicle, $5.25 (Amazon Add-On item)
Play-Doh Classic Fun Factory Playset, $5.48 (Amazon Add-On Item). I had one of these growing up. Comes with 8 one-ounce cans of Play-Doh, huge value item.
