This ruling used to exist on the AEG forums, so figured I’d ask here so we have an official reference.
Pettigrew’s Pawnshop:
After a player plays a non-Gadget goods, this deed’s controller gains 1 ghost rock.
Do you gain 1 GR for bringing cards into play via General Store, Doomsday Supply, or other affects that “attach” a goods to a dude/home or otherwise bring it into play outside of Shoppin’?
