However I just googled it and discovered that it is a supermarket in Alaska. Not many of us on here are from Alaska so you won't find many first hand experiences. I did also see that it was purchased by Safeway a few years back. I have bought tickets from a Safeway here in CA and have had no trouble using them.
Never heard of carrs...but if they are the plastic tickets like they sell at Safeway I too have used them and they work great . The ones from Safeway can be used right at the turnstiles, and no need to exchange for another ticket.
Are you referring to Carrs Quality Center, the supermarket? That's the first thing I thought of. We don't have them down here though, so I probably couldn't help much.
