I opened a Chevron gas card during an app spree in April. My hope was to get a visa with them, but I only qualified for a store card. No worries because they were giving me a 30 cent rebate on gas. I PIF every month and when I checked my account just now, I noticed that my CL went from $650 to $1K. I didn't even ask for a CLI.
Who knew Chevron wanted to celebrate the 4th with me?
