I think AEG internals and upgrades, that is stocked more and not special order as often (maybe causing them to be slightly cheaper as they are brought in more bulk then 1 ofs). So far most of the upgrades I've order, have been on group orders to reduce the costs for the 1 of orders. Do knot if that would work for you guys due to the over head end, but it sure would make me but more from a retailer then waiting for a group order.
