Amazon offers the Fisher-Price Roller Blocks Rockin' Wagon for $21.98. At checkout, it drops to $17.58. Plus, Prime members bag free shipping. (Non-members can spend $35 to bag free shipping; otherwise, it adds $7.69.) That's $4 less than buying it at a local store, although we saw it for $3 less a month ago. It features a clicker wheel to stack the roller blocks, peek-a-boo flipper to flip blocks onto the wagon's rockin' ramp, and a flag with noisy clacker bead.
