Target offers the Spalding NBA Street Basketball in Official or Intermediate for $10.59. (Amazon ships both sizes for the same price for Prime members; Walmart offers both sizes for the same price via pickup.) Choose in-store pickup to dodge the $4.99 shipping fee. That's tied with our mention from four days ago of just the official size and the lowest in-store price we could find for either size by $4. It features an outdoor cover and wide-channel design.
