Buying book lots and reselling on fba

Hi, I’m new to amazon fba and have heard that selling used books is a great way to make profit on amazon fba. It’s a little difficult for me to source books from thrift stores so i thought about buying book lots on ebay and reselling them on amazon for a profit. Does anyone have any experience with this? I’ve gotten ungated in books already. Just need to source them now.

Here’s an example of what I’m talking about. Each book is a dollar and some cents pretty much.
