The way chains such as Baskin Robbins work is this: they're franchises. This means that franchisees buy everything they sell from the parent company. And that parent company provides those products based on their own bottom line and their own convenience. And it's not convenient to provide out-of season products. So the short answer is, probably you won't be able to order that summer delight they only sell in the summer. This is the reality of doing business with big corporations.
