Hi there! I understand you're having trouble checking out at Walgreens, and you're seeing three bouncing balls on the screen. That sounds like an issue with the checkout process. I’d love to help you sort this out!

To better assist you, could you let me know:
- Are you using the Walgreens website or the mobile app?
- Have you tried a different browser other than WebKit on your Windows 10 computer?
- Have you cleared your browser cache and cookies? This can sometimes resolve checkout issues.

Once I have this information, I can provide some more targeted steps for you. Thank you!

Walgreens website. I have tried Google, Brave and Firefox. I cleared my cache and cookies a few days ago. I also call Walgreens CS, they were unable to help.

Thank you for the details! Since you've tried multiple browsers and cleared your cache/cookies recently, let’s explore some other options to get you checked out successfully.

1. Disable Extensions: Sometimes, browser extensions can interfere with website functionality. Try disabling any extensions you have in your browsers, especially ad blockers. Here’s how to do it:
- In Chrome, click on the three dots in the top right corner, go to "More Tools," then "Extensions" and toggle them off.
- In Firefox, type about:addons in the address bar, click on "Extensions" and disable them from there. If you're using Brave, the steps are similar.

2. Try Incognito Mode: Open a new incognito window (or private browsing window) in the browser. This mode disables extensions and may help you bypass any caching issues temporarily. You can do this by pressing Ctrl+Shift+N for Chrome or Brave, and Ctrl+Shift+P for Firefox.

3. Check for VPN or Proxy Settings: If you’re using a VPN or any proxy settings, try disabling them temporarily. Some websites may not function properly with VPNs.

4. Firewall and Security Software: Your firewall or security software could be blocking elements of the Walgreens website. Consider checking that to ensure it's not causing the issue.

5. Update Your Browsers: Make sure all your browsers are up to date, as outdated versions can sometimes lead to issues with modern web applications.

If you've tried all of these steps and still can’t check out, I recommend contacting Walgreens Customer Service again, as they can assist further with technical issues. You can reach them at [email protected].
