Microsoft is really messing around with the ultra upgrade in Killer Instinct

Looks like this 'deal' was only valid till 26th of May.

I commend Microsoft for experimenting with the pricing model but if you offer a "pay for what you use" model it has to be consistent.

$20 upgrade to the Ultra pack should be a permanent option.
