Product found in a supermarket cart

I found a product in a supermarket cart at the cart station in the parking lot of a shopping center, in an area with a mixed population: charedim, religious, secular people, and non-Jews. The place is not guarded, and I took the product. Am I obligated in the mitzvah of returning a lost object, or may I acquire the product for myself according to the laws of lost property?

Shalom u’vracha 

You may take it for yourself. 

This is an item without any identifying sign, and due to the nature of the place, the owner gives up hope of its being returned.
