Where did you hear that? Have they actually received Top Tier status yet? I ask because down here in Cochise county we have a buttload of massive Circle K stations, including a new one going up near me. Currently I have to drive into town for Union 76 to get Top Tier at a reasonable cost (a couple of Chevron stations closer, but both are 50c above every other brand - funkdat).They're converting nationwide but because of public demand they are adding the detergents necessary to become Top Tier.
We used to have a bunch of Giant stations that sold Shell at cheap prices, that was great. Then Speedway bought the chain a couple of years ago and sells their own non-Top Tier swill at similar prices.
