Rather than advertising and publicizing your products and services directly on social media and group chats with your personal account which isn't bad but also not very professional, you can publish your works on our store for free and we'll let the whole world get to see them.
For instance, Chidimma is a fashion designer or she sells ladies wear. She can post them on our store, with the price, snapshots and other description. Then people can get to see it and buy/order for them. She can also decide to share or invite her friends on the social media to the product page using a link.
Maybe you don't sell but you render services or have a special skill, you can publish them too on the store, all for free.
