The resource High Definition Commentary: Philippians is incorrectly set up for Dynamic Pricing in Reformed Portfolio (it seems to be fine in the standard base packages).
It's showing up as having a value of $199.95, rather than it's actual value of $29.95.
I think it's very likely that it's configured with the Greek Discourse bundle SKU, but labelled as High Definition Commentary. I don't know whether the label is wrong, or the SKU is wrong.
