Newtrent offers its Newtrent Tempered Glass Screen Protectors for iPhone 5, 6, or 6 Plus for $11.95 each. Coupon code "SUMMERBLAST" cuts it to free. With $1.95 for shipping (select "First-Class Mail Parcel" to have it drop at checkout), that's a savings of $14, tied with last week's mention, and the lowest total price we could find. It resists scratches, fingerprints, dust, and normal wear.
