check with the people in the marketplace room at marihemp too. they'll be glad to give advice on someone before you do biz (but don't bother asking for names). some sellers refuse any mention of their name in public tho so in some cases that won't work and you'll have to either go by instinct or ignore them.

there used to be more doing biz by CAD (cash after delivery) but it works both ways with scams...there are plenty of scam buyers around too. they also make the list at http://scams.da.ru/
