Hi There!
I have large amount of followers on the both major platforms Instagram and Twitter that you have asked to promote your shop on the social media for increase in sales.
I have placed 3 days delivery time, because I will promote your product on the both platforms Instagram and also on twitter for three days with my best try as I can do.
I know how target the related audience, which is probably more important to sale the product in the specific field or on over all bases, we can discuss it more in the communication section, and also on price promotion timing further in details.
I look forward to hearing from you soon!
