Heya mate. To try and answer your questions - If your trying to sell some to a club on consignment, yes you generally ARE allowed to re-claim any unsold bud at any time. But it depends on each collective b/c sometimes they take ur bud and bring it to another branch of their collective or even other dispensaries. About the 8 lbs - Im not gonna say anything conclusively, but im pretty sure that most won't even fuck with that much weight at once. When it comes to collectives, the most I have ever dealt with at once is 1 lb. In the past I have gotten paid for a half, and left the other half on commission. Again it depends greatly on each collective. It couldnt hurt to down to your local club and ask them. Remember - most clubs won't want to deal with you at all until you've done some regular business with them and know them pretty well.
