Accidentally bought a display item

It’s my first time purchasing at bath and body works. I didn’t know that you could accidentally purchase a display item. When I went for the first time it was pretty packed since the 75% sale is currently going on. I grabbed what smelled nice and quickly went to check out.

The check out process was speedy since the line was long. So the cashier didn’t catch I brought a display item. I didn’t notice until I got home.

Is it possible to at least get store credit?
