I am ordering some small gas generators from overseas and wish to sell them online. Amazon looks interesting but what other sites, gauged for selling in Canada. Do I need a website? What is the most prosperous way?

A web site is never a bad thing, but the issue is that you have no one coming to your web site.

Ebay is a standard way, and a eBay store is a way 1000's sale items.

The issue with profit is price you pay and what the normal retail online price is. I will assume you already know those pricing. Also have to consider the return policies, and how one return will efect your profit
