It appears that the store library is only for executive corona subscribers. As far as I can tell all of the tutorials only mention using IAP’s with “store”.
I have checked out a few tutorials and all of them mention using this library for IAP’s such as the one below.

If I can’t use “store” as a free user, where else can I turn to implement IAP.
