if you can't find an mmc, check craigslist (often they get flagged allot). as a legal patient, you should not be in any legal jeopardy for doing so. Take papers and ID with you. Don't go high.

You'll get much better prices there. Be careful and inspect weight and quality before you buy. You can find much better than many MMCs and much worse. Be smart about where you meet, etc, just like any craigslist transaction.
