I have found CSG to grade exceptionally harshly - I sent nothing I thought would grade less than a 9. I barely got anything over 8.5! Check out the condition yourself in each of the photos - I have no doubt many will do much better if regraded elsewhere.
Pick up is available from malabar and im always happy to combine postage - single slabs will be sent in tracked envelopes while multiple slabs will requires a satchel.
