not really recommended.. selling is against forum rules for sure... and a lot of people even get nervous just asking where they hail from from strangers... hang around awhile, i'm sure you'll make some friends in due time..
there are also some sections of the forum that are dedicated to certain areas of the country... check them out and see if there's one for your area..
but going around and asking people if they sell is one sure way to send up a lot of red flags in my opinion..
