Welcome to the boards, Kristen!
You will usually find canned chipotles in the mexican food section of the grocery store. If you can't find them at your regular grocery store, TJ's or WF should carry them (I think). They keep almost indefinitely in the fridge once opened, so you shouldn't need to buy them very often. I have no trouble finding them in my remote part of the US (Bismarck, ND), so I'd be surprised if you can't find them where you are.
