May I know the difference between : This model =>https://www.galaxus.ch/it/s1/product/amazon-kindle-oasis-2019-special-offers-7-8gb-ereader-11540586 and this => https://www.galaxus.ch/it/s1/product/amazon-kindle-oasis-2019-7-8gb-ereader-11577605 They both look identical in term of specs, but can't really figure out why the price differs (269.- vs 349.-) The only change I was able to spot is 1 millimetre less in height and little bit lighter (10gr).
