Bought a 12.9" Wi-Fi for delivery on launch day. Decided in the end I wanted an LTE model so returned it. Regretting it a bit now as it was perfect. 1st LTE had a dead pixel so returned that. 2nd LTE I opened today is bent. Properly bent. I've never returned an Apple product before these issues, had many. Now I don't actually mind returning and buying a new one as I live in a large city and it isn't that much hassle. However, the question is will Apple at some point say you can't keep returning and buying the same item? Thanks.
