What is the difference between Aliexpress & Alibaba?

The main difference between the two is Aliexpress focuses on dropshipping and Alibaba focuses on wholesale and customization.

I found the perfect product on Alibaba, can I use it?

Cortney suggests focusing on dropshipping until your store is bringing in income. Dropshipping is the best way to keep costs low until you can invest in a customized, wholesale product. So yes, you can, however, it is not what is suggested in the first stages of growing your business.

I found an Alibaba supplier that dropships, can I use them?

Absolutely, however, keep in mind you will need to manually import these items or find an app that will do it for you, DSers only connects with Aliexpress.
