Can confirm: They sell dry ice by the pound. They place the dry ice in a paper bag, so you should bring a cooler and gloves to handle it.
Ice Cream World, Allentown, sells dry ice. I've taken in a small (very small) cooler and they've given me a pound or so in a paper bag for a very reasonable price.

They give dry ice in emergency blackouts. Maybe they sell it.
