How do i get a legal thc drink at whatever wholesale price the vendors pay that makes it profitable to sell to me

Do i need to buy like so much of it? Do i need to have a company or some sort of license? Can I just lie my way into appearing to be a vendor but just buy bulk for personal use? Do i even need to lie? Can i just be like "give me a thousand cans of the dank shit"

These 30mg thc drinks are basically medicine in a can for me like my sleep hasn't been perfect but it's been so much better. I think if I could pay whatever rate the vendors do that makes it profitable to re sell to me at $5 a can then i could finally not spend a shitload of my income trying to chase a high to help me sleep (and instead spend a more modest but still expensive portion of my income actually sleeping).
