Amazon offers a LeapFrog $20 Digital Download Card for $15. At final checkout, the price drops to $7.50. Plus, Prime members bag free shipping. (Non-members can spend $49 to qualify for free shipping; otherwise, shipping adds $6.03.) That's $6 under our October mention and the lowest total price we've seen. (It's the best now by $12.) This card can be used to download learning games, eBooks, audio books, videos, music, and more from the LeapFrog App Center.
