see craigs list. as a buyer, there is no legal risk purchasing from CL in CO any more for anyone now w/A64. If not a med patient, just stick to 1 oz or less.

see boulder and denver craigslist. search for mmj or ounce or strain, etc. (use only one term at a time on craigslist, works better)

just be sure to look at quality and make sure it's worth it. there arre some great deals on there. Gotta keep checking back as if there is a caregiver with a few extra ounces, he'll likely only have his ad up for a few hours, till his Z's are gone. So if you find nothing, check back tomorrow.
