For in-store pickup only and with stock varying by ZIP code, Kmart offers the Otterbox Defender Series Case for Samsung Galaxy S5 in Glacier for $39.99. Plus, Shop Your Way Rewards members earn $39.59 in SYWR points. (Not a member? It's free to join.) Assuming you use the credit, that's $17 below our refurb mention from May and the lowest price we've seen for this case. (With the credit, it's a current low by $22.) It features a plastic screen protector and belt-clip holster.
Of note, Shop Your Way Rewards members will earn a Kmart credit with purchase and may be eligible for additional credits and discounts.
