A:AnswerMy original screen was a Lifetime and I think it was $15-$20, and to have someone at Best Buy replace it was $8. Mine was free replacement and I paid to have them install it.
A:AnswerI it breaks later just bring in your receipt with the phone and you will get a free replacement. If you want them to install it, however, there is a service fee of about $7 no matter who installed it last.
A:AnswerThis particular zag screen protector will not work on an iPhone 8 plus. However, if you find the appropriate sized ZAGG tempered glass screen protector for your particular iPhone 8 plus this would be a good option. The only other screen protector that I would recommend is the OtterBox Alpha glass. I have installed those on several phones that I have owned in the past and they have performed superbly.
