What’s the difference?

What is the difference between a shopper and a shopper-holic. A shopper goes to the shops to buy something they want. The shopper-holic goes to the shops to see if there is anything that they can want to buy. On a biochemical level, the shopper-holic needs a dopamine fix before they get a seratonin boost. Dopamine is the wanting hormone, (the aptly named addiction hormone) seratonin is the blissed out because i got it hormone. Whoever would have thought shopping was so hormonal?
