Spendorphins 

Hormones released by the human brain when a lot of money is spent. Found predominantly in females.

As Hannah drove her new Mercedes from the Showroom she could hardly contain her delight as spendorphins rushed through her body.

Spendorphins 

The flow of energy that starts in your body and mind when you go into a store that has things you want to buy.

I went to Barneys and got a rush of Spendorphins as soon as I walked in the door!
