Haha just read this thread, first off OP love the gringo coins line, my wife is mexican and I'm from the UK and she always laughs at how much of a "gringo" I am when I can't handle spicy food like she can so I'll be using that term for my currency now with her to make her laugh, second, this thread is funny as fuck seeing what I can assume is Americans thinking Sony can cancel orders and not honour a price mistake they made and advertised, just a heads up to Americans but a lot of countries have consumer rights that aren't shit level, if a company doesn't do their job right to make sure a price is correct before an item is displayed as that then yes they should honour it.
If I walked into a store here and they have a price for an item listed on a price tag, I go to the counter and they say that's the wrong price tag and refused to honour it, then they are legally wrong and will have the business regulator etc deal with their breach of law, I've had this happen to me in person and the moment I point out a price tag says something different on the price they asked for they change it to match the price tag.
Online isn't different, if they can't do their job right and wait until a customer is buying or paid for an item to change price upwards that's not legally right in any way. It's fucking upselling the price once they know you want an item and are paying or paid for it.
Man Americans really gotta get some perspective other than eating corporations shit they hand to them.
If you want some extreme detail into how far this can go bad for a company outside America, look up the story of a vacuum company in the UK years ago who advertised a free flight for a holiday with every purchase of their vacuum cleaners, but didn't list the price the flight could be, the company was forced to honour the cost for flights of people who got a hoover before they realised the error and it cost them insane amounts of money to pay for tickets to far destinations. Just because the usa can't put consumers above corporations doesn't mean the rest of the world won't.
