No, this includes everything. Houses and cars specifically. These aren't retail. The data is true no matter how you slice it and as I said it is about all the money spent in the economy including big ticket items like houses and cars, not just retail as you falsely suggest.
If you are interested in data also check how many percent car purchases are done because wife wanted them. Cars salesmen in their training are specifically told that a guy showing up without wife isn't serious about the purchase. They will always tell you to come back with wife. Because she is the one telling the guy to pull the trigger. You just pull the trigger. But you won't do it without her approval. The same with house.
