Ok, I really don't get on with JSON stuff?
$.getJSON("jsonOut/products.aspx?barcode=yes", function () { alert(data.label);  });

$.getJSON("/jsonOut/products.aspx?barcode=yes", function (data) { alert(data[0].label);  });

$.getJSON("/jsonOut/products.aspx?barcode=yes", function (data) {
   for (var i = 0; i < data.length; ++i) {
      alert(data[i].label);
   }
});

$.getJSON(
     "jsonOut/products.aspx?barcode=yes",
     function (data) {
         alert(data.label);
});

[
   {
        "label": "Boss TR-2 Tremolo Pedal",
        "price": 79,
        "id": 1287
    }
]

data[0].label

console.log(data);
