Shipping Rate Incorrectly Calculated (Sometimes) - JavaScript Blocked?

I have the following custom shipping logic setup in the store at
<script type="text/javascript" charset="utf-8">
FC.checkout.config.customShipping = {
  onLoad: true,  // Set to false if you don't want shipping calculated when the checkout loads
  onLocationChange: true // Set to true if your shipping logic relies on updating whenever the shipping location for the order changes
function calculateShipping() {
  var shippingCost = 0;
shippingCost = 12;
var coffeeProducts = 0;
for (var p in fc_json.products) {
	if (fc_json.products[p].category == "coffee") {
		coffeeProducts += fc_json.products[p].quantity;
if (coffeeProducts > 0) {
	if (coffeeProducts == 1) {
		shippingCost = 5 ; // $5 for one coffee product
	} else if (coffeeProducts < 6) {
		shippingCost = 11; // $11 for less than 6 coffee products
	} else { // free for more than 6 coffee products
		shippingCost = 0; // Free shipping because they bought so much

if (fc_json.hasOwnProperty('coupons')) {
        shippingCost = 11;

The shipping should be:

1 bag of coffee= $5.00
2-5 bags of coffee = $11
6+ bags of coffee= FREE

For some reason, there is an occasional user who purchases a few bags of coffee and gets FREE shipping. Can't figure out why. Is it possible that blocking Javascript would cause this?

    If javascript was blocked, the customer more than likely wouldn't be able to check out at all - as our checkout heavily relies on javascript.

    Could you whisper me the transaction id's for the transactions that didn't have shipping that should have?

    I think this might come down to a 'console.log' function call in your custom shipping code - which if present some browsers will break at that point - which is right before the shippingCost is actually applied - which means shipping cost will stay at 0.

    Try removing that line, it looks like this:

    and let me know if any other orders come in where the total shipping is 0 when it shouldn't be.
  • Thanks! Removed it and will keep you updated.
