Earn with the help of dropshipping

I am much into on-line business, that is e-business. I work from home, and do avail the services of dropshipping companies. I have been dealing in electronic products till now. Looking to the market trends, I want to increase my product range and include more products. Where can I get an idea of which goods to include and which not?

Since you are already into the on-line retail business, you must keep updating your product range. There are many sites with relevant details on the internet.
