Cherryz contacted her, just like how they contacted Hyacinth (Mrs M) and other resellers, They do a lot of sponsored stuff in the reselling community. especially the Instagram lot. so yes she would be on their radar seeing as they mainly focus on the vloggy and bloggy youtubers and instagrammers who are also resellersShe obviously contacts them first, she'd not be on their radar otherwise. Such a healthy shop that was!!
Carla is also a great person in the sponsors eyes. her cherryz haul has 3.1k views it cost the company £50 to get that amount of traffic and all they need is for people to spend £250 and they are into profit on the sponsor, which is easy to get (based on a %20 profit markup per item sold)
