Are there businesses that sell maple syrup
Yes. Big supermarkets in big cities sometimes have it though not always. Most is Canadian, however this company in Poland sell an American brand called Cary's by mail order.
The website is in Polish, however if you need help with that, anyone here will provide it.
edit. It's about $10 a bottle plus postage, but products from one country in another are often expensive. And it is maple syrup!
