Honestly, this is the same way I think of it.
Apple charges pretty high prices and going directly through Apple Store, there's no retailer taking a cut of the profit. I expect returns is something they already account for. They probably gain more sales by allowing 14 day hassle free returns compared to losses incurred. Thanks to their return policy, I know I've bought a few Apple products I was undecided on that I ended up keeping.
Now folks who return and exchange products 20 times due to some issue you'd have view with a microscope, yeah, that's a tad excessive.
I don’t know if it is the case but I think that small Youtube channels who review Apple products ( I don’t meanthe big ones to whom most probably Apple send the unit to be reviewed ) they buy, review and return it.
In europe we don’t have this return policy I think or even if we do, many do not know it or not use it like in America. I find it wrong, but I don’t judge who does it, it is just my thought. Then I can see how nice it would be, if i could buy both 12.9 and 11 inch iPad and try them both and see which one I like in everyday life. But I feel like many does it excessively, and at least ethically I find it wrong.
But well, on the other hand, it may be good for people who wants to buy an affordable Apple product as they could buy it like open box item and have a better deal on it. That’s definitely a good side of it, unless Apple repacks them and sells them as new ones, again, which I don’t think so, but I don’t know well.
