The order has to actually go through the dealer - as opposed to ordering online for oneself. So, I cannot imagine a dealer would allow someone to order many IGs without a binding contract.
That said, however, if dealers are playing games but one (or several) are not, there is nothing stopping "us" from collective buying. That is, because XYZ dealer is fair and honest, 15 of us can order through that dealer to avoid a less scrupulous, albeit closer, dealer.
