Hello Kevin,
Thanks for pointing this out. The $83 price is a left over from the period when Eventide was allowing owners of one of the plug-ins in the bundle to upgrade for only $99.
That offer ended some time ago and the the Bundle upgrade went up in price to $179. It has changed again with the new additions to the bundle and is available exclusively on the Eventide website according to how many of the plug-ins one owns.
Sorry for any confusion this might have caused.
Best regards,
