Let's just say if you get too adventurous ordering some of the more ".interesting" products, along with your BAC, from this vendor, you will get a call requesting your license.
If you're unable to provide it, you'll receive an email stating your previous orders containing Rx Only products were shipped in error, and steps would be taken to ensure all Rx products would no longer be sent without a medical license verification or prescription.
Mountainside Medical no longer ships BAC without a license.
Perhaps someone could try CIAMEDICAL (search for 00409397703) and see if they have any luck. It's a few dollars more but free shipping I believe so its effectively the same or cheaper, Otherwise I don't know of any other vendors selling cases without a license.
