I know Amazon has it cheaper but Samsung has replaced the battery and provides a 1-year warranty. So I look it as that new battery and 1-year warranty costing me $160. Also Amazon does NOT give me a discount for being a government employee, Samsung is taking off, if I recall correctly, $147 for that. So, the phone would normally be $650 with the new battery and warranty but ...$343. I could buy from Amazon renewed but I'd get, I believe, a 30-day warranty and a battery with no less than 80% life. As someone that normally demands the purity-of-perfection that a brand new manufacturer-sealed device ensures...the Samsung Certified Re-Newed phone seemed like the next best thing. Because one scratch, one mark, is one scratch too many.
