Please point out what regulations you speak of, and why they are in place.
For example, vape pen regulation imposes requirements such as maximum nicotine concentration and minimum acceptable purity, and must be child-resistant. Regulation prevents you from trying to sell hazardous vape pens that can and will pose a health risk. What spark does this fire in you?
Or would you prefer to blindly resell things that harm the people around you without being bothered about consequences?
