For in-store pickup only, Walmart offers the SOG Specialty Knives & Tools Key Knife in Blue, model no. KEY-108, for $7.97. (Field Supply via Amazon charges the same for the Pink version with free shipping for Prime members.) That's tied with our mention from last week and the lowest total price we could find by $1. It measures 4" overall (with closed length of 2.5") and features a 1.25" 420J2 steel blade with a drop point shape.
