Sears offers the Marvel Iron Man Case for iPhone 5 for $7.99. Opt for in-store pickup to avoid the $6.50 shipping fee. That's tied with last weeks mention as the lowest total price we could find by $6. The case is shock-absorbent and prevents scratches.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
