Bought a "new" retina MBP from a major Amazon reseller. Opened shrink-wrapped box and noticed no cellophane on the MBP's screen, as is usually the case. This made me suspect the MBP was, at minimum, open-box or even refurb rather than new. Then checked About This Mac > System Report > Power and saw that the battery's cycle count was already 7. (Everything else is fine; the specs are exactly as ordered and the screen is great.) This is clearly a used MBP, right? Thanks for all feedback.
