Ok, so if we bought the regular Sumerset(I did), and now would like to upgrade to the collectors, is there any way to go back and add that for the additional $10 instead of having to pay the $39 for it(after paying the $29 already)?
If you wish to upgrade to the Summerset Collector's Edition from your current Standard Edition, you would need to purchase the Collector's Edition Upgrade at it's current price.
