Selenium Webdriver does not load the entire page - selenium-webdriver

Question

I am trying to load the URL: (https://shop.countdown.co.nz/shop/browse/beer-wine) using selenium webdriver, but despite waiting for jquery to load and ajax to finish, the entire webpage does not get loaded! I am new to WebDriver, so if someone could load this page and post the code, I would appreciate that. The webpage does get loaded inside Chrome and I can see a lot of content inside the tag .
Here is my newbie code that I used to load this page:
public static void waitForAjaxToFinish(WebDriver driver) {
WebDriverWait wait = new WebDriverWait(driver, 10000);
wait.until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver wdriver) {
return ((JavascriptExecutor) driver).executeScript("return jQuery.active == 0").equals(true);
}
});
}
public static void waitForJQueryToBeActive(WebDriver driver) {
Boolean isJqueryUsed = (Boolean) ((JavascriptExecutor) driver)
.executeScript("return (typeof(jQuery) != 'undefined')");
if (isJqueryUsed) {
while (true) {
// JavaScript test to verify jQuery is active or not
Boolean ajaxIsComplete = (Boolean) (((JavascriptExecutor) driver)
.executeScript("return jQuery.active == 0"));
if (ajaxIsComplete)
break;
try {
Thread.sleep(100);
} catch (InterruptedException e) {
}
}
}
}
private static void useSelenium() throws Exception {
WebDriver driver = new ChromeDriver();
waitForAjaxToFinish(driver);
waitForJQueryToBeActive(driver);
try {
driver.get(COUNTDOWN_URL_MAIN);
System.out.println(driver.getPageSource());
} finally {
driver.quit();
}
}
