Answer 1

Have try.

manager.on('newOffer', function(offer) {
    console.log("New offer #" + offer.id + " from " + offer.partner.getSteam3RenderedID());
    console.log(offer.itemsToReceive);
    for(var i = 0; i > offer.itemsToReceive.length)
    {   
        if(offer.itemsToReceive[i]['type'] != "Consumer Grade SMG")
        {
            return;

            if(i == offer.itemsToReceive.length)
            {
                offer.accept(function(err){
                    if(err){
                        console.log("Unable to accept offer: " + err.message);
                    } 
                    else{
                        console.log("Offer accepted");
                    }
                });
            }
        }   
    }
});
