I understand how you feel - and in your position I am sure I'd be thinking the same thing.
However, the price on the webpage was a typing error by a single individual in the admin team. Adorama doesn't actually make a charge until an item is shipped, so nobody actually lost anything.
It does say on the website:

I do want to add my apologies to the company apology to anyone who was disappointed, as a result of this genuine human error - and however fed up you are right now, having spoken to the guy who messed up on this one, I think he may be in a worse place....
