Amazon offers Prime members a selection of Batman Hot Wheels Cars for $9.99 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise, shipping costs $6.11.) While that's list price, it's the best current deal we could find for these limited edition and hard-to-find models. Each is a 1:50 scale replica of the movie and TV show vehicles. A few best bets:

• Hot Wheels 1966 Batman Batcycle Vehicle for $9.99
• Hot Wheels Batman vs. Superman Batmobile for $9.99 (pictured)
