the supply is low, just look at all the stores that don't have gas, the rise in cost is due to low supply, I know of several QT's ( I work for QT) that are out, and have been out for a few days, and some other stations that are in the same boat, all the price mark up is legit, we aren't running out in the whole scheme of things, but our supply coming from the west has been all but cut-off
