Walmart continues to offer the Safe Inside Portable Security Case in Blue, model no. 4500B, Pink, model no. 4500P, or Green, model no. 4500G, for $17.30. (Amazon charges the same in Blue, Green, or Pink with free shipping for Prime members.) Opt for in-store pickup to avoid the $5.97 shipping fee. That's the lowest price we could find by $8, although we saw it for a few cents less in August. It features a 3-digit combination lock, retractable 7" vinyl-coated steel locking cable, and measures 1.2" x 3.9" x 9".
