When I was doing a Civic radiator change a few years ago, got my local dealer to do a price match for Type2. I was vague about whether it was another local Honda dealer or an online price. Got him to match at $15 and change, which was a great price for it then. In addition to a couple gallons Type2, also purchased a tstat and a couple OEM hoses below list and I've bought parts there before. Back then it was $19 and change a gallon list, which ime is generally what like to get if they can. I did the same (price match) with some wiper blade refills too. Never hurts to ask. But if they want to include the online price including shipping, usually more than paying list at dealer.
All that said, at ~$14/gallon currently for the PepBoys OEM Blue Concentrate, if one was nearby that's what I'd be using. Great deal, not sure how long it will last as regular ~$22 gallon.
