@PNS The reason it's $450 per ticket is because they were hoping to recoup the cost of the wedding by making everyone else pay for it by charging them.
$450 goes FAR beyond paying for what you would spend attending a wedding (i.e. food, cake, etc.) These idiots were hoping to have a lavish wedding and get everyone else to pay for it.
The fact that they expected their black relatives to have that kind of money makes the story even more absurd.
