Yes, this is not obviously deflationary. Especially when it's a resource that contributes to market inefficiency, like transportation costs. If it becomes cheaper to move things from A to B, then price differentials between A and B become harder to sustain. (that can contribute both to price falls as well as price increases - if it costs less to export something to a foreign market, domestic consumers might have to pay suppliers MORE to persuade them to sell the item locally rather than ship it overseas).
