GameRager: What if it's a consumable item(food/etc) or something else they cannot put back on the shelves once one uses it(in whole or part)? Should the stores eat the cost every single time?
You did read at the end of that sentence, where I said .... but it's just not that simple.
So in short, if you ate it, you cannot return ... unless you only ate a portion and there is something wrong with it ... off or not what you paid for ... happens all the time.
Many other products are often returned to stores, because the buyer feels they are not what they said they were or don't work as stated.
With digital products though, it is a lot more complicated, especially without DRM ..... hence why I said ... but it's just not that simple.
And I personally feel, that if you walk into a cinema, start watching a movie, and leave before half way, you should be re-imbursed or at least get a portion back. You did not get the full product, and clearly you disliked it ... else you would have stayed. The only exception to that, would be if it was a full-house, so your seat could have been used by someone else ... in that scenario, the cinema actually loses money if they reimbursed you.
GameRager: With amateur reviews/twitch streams/Let's Plays/etc that should not be as big a problem. People need to be smart shoppers and not make companies pay the cost for their mistakes so often.
Reviews etc can only tell you so much, and not everyone is prepared to or should have to be, to go out of their way to check things out as much as possible.
Advertising is a license to tell all sorts of lies, that are all too easily gotten away with when they happen, especially if they make things ambiguous enough.
So you can't just label it as the buyer's mistake, as often there are things the sellers do to mislead etc etc.
The biggest mistake us buyers can often make, is to trust the seller too much, but that often leads to an impasse, so naturally we are driven to take a risk. That doesn't make the seller less liable.
