networkn: Man there are some days I despair for the future of our country! It was a mistake, any idiot could tell that. There are legal protections in place for a good reason, and it's fair.
HN aren't my favourite company, but good grief, the fact they gave a $100 voucher when they had no obligation to do so, is good customer service.
It was such an obvious mistake (on the cheapest set at least), that I actually hope the $100 was a gesture for the email stuff-up rather than for the pricing mistake.
