Found a product that competitors are selling with 300% margins on Amazon

So i found a product on Alibaba that in my local market is being sold at minimum 200% to 300% margins. There are several sellers on Alibaba selling the product so I know that is the legit price. The cost price includes shipping, customs and all related fees.

Did I find an amazing niche that I should jump on or there something I am not seeing?

Also I know its the same product since the amazon listings just use the Alibaba pictures.
