Shopping issues

I suppose I'm getting older but a habit is a habit. As it happened last evening. I've got out of the subway and due to this cold November weather and the flu my lips are very dry. So I thought why not buying a lip balm. Firstly I went to the pharmacy. I opened the door I saw the queues and got out as quickly as possible. But stubborn me wasn't satisfied with the situation so I got to the supermarket. I went straight to the cosmetics shelves. While there, I began searching for that lip balm. Meanwhile in my hands landed all sort of other things that I thought might be useful. So by the time I got to the queue in order to pay my shoppings I realized I had dental floss but no lip balm. Then revelation stroke me: what am I doing here with this dental floss thing in my hand when I entered the supermarket to buy something else? Is my shopping impulse so strong that if I don't find what I need I'll buy something else just to buy something after all? So I put everything back and got out of there God speed. I do have some shopping issues. Is there a treatment for that too?
