Facebook Shop?

Hello Group,
I hope you are well, I have a super active Football Page and I opened the Shop option and introduced different jerseys.
Then I had a lot of interest from the fans but I do not know how to continue the rest about making payments or sending T-shirts by post.

you can do drop-shipping with AliExpress not just aliexpress there are lots of service who offers drop-shipping like CJ drop-shipping etc, Google it
