Yeah, I have that same question also. It used to be that the gas cards were not affiliated with visa or mc. Now when you get a gas card they have either mc or visa on them. If this is the case, what is the difference between having a visa or mc gas card and having just a regular credit card? How do they distinguish between the two?
It gets reported to the CRAs as a REVOLVING credit acount. The only difference between a Visa/MC and Store card is the comment on it, Visa/MC will generally say "Credit Card" while a store card will generally say "Charge Account" or "Charge Card".
