How to monetize unique opportunity i have right now? Suggestions ?

I have a huge supply of 1 products which is very hard to come by right now in my whole country. Even i am top seller with everyone out of stock. whatever stock i sent truck load of supply to my FBA warehouse and it gets sold in few days. I am purchasing this product at 1/3rd of selling price. How to monetize this opportunity and make most of it? Should i try to find wholesalers or something?
