Since there is variation in the Pick-A-Brick selection from store to store (for the time being), I thought there might be a desire for a collective effort to procure desired elements not available locally and provide others with the same opportunity from your local selection.
Doing this, of course, greatly hinges on current inventory tracking. I think we can leverage the great platform provided by iPaB at BrickBuildr: http://www.brickbuildr.com/view/pab/
Minimally, I think this effort would seek to provide a contact person for each store that is willing to field requests. I imagine the requests would be accepted at the discretion of that person.
If you're willing to be a procurement person for your local store, please post to this discussion and I'll get you added. I'd also like to solicit ideas for ground rules (i.e. Payment expected in advance, order minimums and maximums, quantity tolerances, small commission to offset travel costs). I really think LUGs could step up to cover their store as a group, and imagine bulk ordering would be most efficient in that type of group format.
Finally, although I'm a member of the Brickset staff, this is being conducted without the endorsement of Brickset, just as all things in the Marketplace.
