    I’m the owner of JustCBD Store label (justcbdstore.com) and I am currently trying to grow my wholesale side of business. It would be great if someone at targetdomain can help me 🙂 I thought that the most effective way to accomplish this would be to reach out to vape companies and cbd stores. I was hoping if anybody could recommend a reputable site where I can purchase Vape Shop Sales Leads I am currently considering creativebeartech.com, theeliquidboutique.co.uk and wowitloveithaveit.com. On the fence which one would be the best selection and would appreciate any advice on this. Or would it be much simpler for me to scrape my own leads? Suggestions?
