Walmart offers the Wilson NCAA Illuminator Basketball for $9.99. (Amazon charges the same with free shipping for Prime members, while Target charges the same via pickup). Opt for in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $3. It measures 28.5" and has a glow-in-the-dark cover material.
Walmart offers the Mongoose Boys' 24" Camrock Mountain Bike in Blue for $99 with free shipping. That's the lowest price we could find by $11. It features 21 speeds, a Shimano rear derailleur, V-brakes, and suspension fork.
REI Garage offers the MSR Nook Gear Shed Vestibule in Green for $49.73. Choose in-store pickup to avoid the $5.99 shipping fee. (You can also pad your order over $50 to bag free shipping.) That's tied with our mention from a month ago and the lowest price we could find by $18. It adds 15 square feet of covered storage area to Nook tents (sold separately).
