Walmart offers the Spalding NBA Street Basketball in Official size (29.5") for $9.97. Choose in-store pickup to dodge $2.97 in shipping
. (Amazon Prime
members can get it for $9.97 shipped.) That's tied with our mention from a month ago and the lowest price we could find now by $6. It meets the official size and weight specifications set by the National Basketball Association.
Update: Walmart has since sold out; however, Amazon offers it for $9.99 with free shipping for Prime members.
