Instagram

Has anyone used Instagram for selling items? If so how did it work out?

many people use insta to push products links promotions
maybe look in the Insta section ?

First create a main account to sell your products, then create a few sub-accounts and use them to comment on and like your main account to expand the reach of your products.
This is usually solved by using an anti-detection browser such as morelogin or multilogin, as many platforms do not allow multiple accounts to appear on one IP.

You can sell via instagram but you need to have a big number of followers to get sales. Good luck!
