Just wanted to give a heads up to the local Overlander members in and around Edmonton. Interstate battery center on 118ave - 159 street is blowing out blue top AGM batteries at $65 a piece. They are reconditioned with a six month warranty. I know they can be upward of $350 new so I'm taking a chance and bought two..they had three pallets and are already down to one pallet left. There is also a $20 dollar core that will be refunded with the return of a old car battery. Does not have to be an AGM they will take any old car battery and there is no time limit just keep your receipt. I would never consider these batteries because they are expensive but this deal was to hard to pass up.
