Through 9/27, these 9" NCAA Throwback Footballs, listed at $17.99, are available for $9.99 at Groupon Goods. Shipping adds $2.99 or is free on orders over $14.99. Even with shipping, this is the lowest price we could find anywhere (select teams are also on Amazon for $14-$18 each). There are currently 23 teams to choose from, but they're selling out fast. Sales tax is charged in most states.
