If you want the covering and it's a good price, then meet at a police station for the exchange. Keep your license plate out of his line of sight. Don't go straight home. Run some errands, make some other stops and be done with it.
Yeah, there's always options. But if it is indeed a little "warm" he sure won't meet at a cop shop! Just get something else, I guess.
I've got two small portion of that stuff.... want to get but just haven't found a good avenue... but well worth it if you can....
