Can someone help settle a bet? In episode #220 a new hardware store at a nearby mall opens and threatens Howard's store. I remember that Howard had to close the store, but I'm not sure. How did this end?

Howard decided to move his store into another location, where there was a pet shop, up for rent

It was a much bigger location, and he renamed it "Cunningham Hardware City". Marion was nervous, because it meant that they would have to refinance the house.

was this because Potsie was involved?
