I've got a Retina Macbook Pro 15" (Mid-2012) and 3 of the rubber feet have come off. I took it to the Apple Store and the Genius Bar representative told me it'd cost $100+ because they replace the entire bottom case. I kind of want to avoid paying that much just to replace the rubber feet. iFixIt only sells feet for Unibody Macbook Pros and the reviews for retina rubber feet on Amazon aren't so hot. So... does anyone have any experience with replacement rubber feet? Any you'd recommend? Thanks in advance!
