Walmart continues to offer the Plano Ammo Can for $4.67. (Amazon has it for the same with a $25 purchase.) Opt for in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from two weeks ago and the lowest price we could find now by $15. It holds 6 to 8 boxes of ammunition and has a water-resistant O-ring seal.

Update: Walmart has now raised its price; however, Amazon still charges $4.67 with free shipping, with orders of $25 or more.
