Which gas station do you guys go to get 93 gas for your z?

Just to let you know, here is what we have available in Cedar Rapids Iowa.
At the Sinclair station were I buy 90% of my gas:
E10: $2.50 a gallon, Plain 87 regular (no ethanol): $2.80 a gallon, 91 (no ethanol) $3.10 a gallon.
At the local Shell station where all the gas is blended with ethanol:
87: $2.55 a gallon, 89: $3.00 a gallon, 93: $3.50 a gallon.
Needless to say, I don't use Shell gas.
