My business is a person on Facebook. Also have a page too. As a person people can msg me and i can reply immediately. I am run off my feet with the amount of business i am getting most weeks.
Insta is just great as i can take photos of all the new stock i get in as i open it up. I've had customers come in and just show me a photo, i grab it, easy sale.
Obviously i get business on texts or phone calls as well but Social media is the best. Free advertising, word of mouth means they can tell someone and they are on my Insta immediately and can see what i stock.
