Posting a Costco station without adding a 'Members Price' comment in comment section of the station is false advertising. The members price is not available to non-members. As a matter of fact non-members can't purchase gas at Costco. Not everyone is aware of that fact. Please refer to Calgary Price Posting Guidelines in the Calgary Discussion Forum (ie 97gmc, 197casey's, Mad Laker's and other member's Costco posts). Thanks for making calgarygasprices.com an accurate price site! Much appreciated buddy.
