Sailor Boy Crackers and Crown Pilot are available at just about every store up here.
Sam's, Costco, Walmart, Fred Meyer, Carrs-Safeway and the bush stores all carry them. They're also available from SPAN Alaska in Seattle.
I'd like to help you out, but I live 600+ miles SW of skAnchorage and it really isn't practical. One, you wouldn't like the bush prices and two, you wouldn't like the shipping.
I don't buy them out here unless I have too. I normally buy them at Sam's and ship them out myself or or purchase through Walmart and have them shipped from their bush order section.
Your best bet probably be trying SPAN Alaska. They ship groceries world-wide and since you're in the L 48 the prices and shipping will be much cheaper.
