It wouldn't bother me. "Ice cold" is just part of the slogan.
The only time I'd care if the soda is chilled when I purchase it, is if I'm going to be drinking it right away, which I generally only do in a food establishment, not a store like Target.
In the posted photo, you can see that there are refrigerated cases, with Cokes in them, only a few feet away near the checkout counter. So if you want a cold one, take it from there.
