My auto-buying code for BestBuy isn't working... why?

Question

I've been trying to get this code to work, but it just won't. (The link is a placeholder, I'm planning on changing it to a 3060 Ti to get one for a home rig.) It also says the goToCartBtn was clicked, but it wasn't.

import time
from selenium import webdriver
#For using chrome
browser = webdriver.Chrome('/Users/admin/Downloads/chromedriver')

#BestBuy RTX 3060 Ti webpage
browser.get('https://www.bestbuy.com/site/nvidia-geforce-rtx-nvlink-bridge-for-3090-cards-space-gray/6441554.p?skuId=6441554')


buyButton = False 

while not buyButton:
try:
    #If this works, then the button is not pytopen
    addToCartBtn = addButton = browser.find_element_by_class_name("btn-disabled")

    #Button isn't open, restart the script
    print("Button isn't ready yet.")

    #Refresh page after a delay
    time.sleep(1)
    browser.refresh()

except:

    addToCartBtn = addButton = browser.find_element_by_class_name("btn-primary")

    #Click the button 
    print("Button was clicked.")
    addToCartBtn.click()
    
    goToCartBtn = addButton = browser.find_element_by_class_name("btn-secondary")

    print("Go To Cart button was clicked.")
    goToCartBtn.click()

    checkoutBtn = addButton = browser.find_element_by_class_name("btn-lg")

    print("Checkout button clicked.")
    checkoutBtn.click()
    buyButton = True

Error Message shown below:

Answer 1

Your goToCartButton selector is not specific enough.

 goToCartButton = browser.find_element_by_class_name('btn-secondary')

Using this selector returns five elements, and Selenium will only interact with the first one it finds, which according to the DOM, isn't the "Go to Cart" button.

Instead, you could use a CSS selector to return the specific element. Using CSS:

goToCartButton = browser.find_element_by_css_selector('.go-to-cart-button .btn-secondary')

And you should be able to click the button now.
