Why are the AliExpress/eBay searches important?

The AliExpress/eBay searches allow you to do research on good sellers. This can be done at any time, and you should be running these.

This is a way to learn from other sellers on eBay as well as work with great suppliers on AliExpess. There is no set time as to when you should be using these or not. They have nothing to do with your eBay account.
