Hi there! I understand you're having trouble adding items to your cart on Fry's Food website using your iPhone. Let's get this sorted out together.

First, just to narrow things down a bit:
- Are you logged into your Fry's account when trying to add items? Sometimes being logged out can affect cart functionality.
- Does this problem happen on both the website through your browser and the Fry's app, or just one of those?
- Have you tried adding different items, or is this issue with all items?

While you check on those, here are some quick basic steps we can try:

1. Clear your browser cache and cookies in Safari on your iPhone:
- Go to Settings > Safari > Clear History and Website Data. Then restart Safari and try again.

2. Try adding items in a different browser app (if you have one like Chrome or Firefox installed).

3. If using the Fry's app, try closing it completely (swipe up from the bottom and swipe the app off screen) and then reopen it. Also, check if the app has an update pending in the App Store.

4. Restart your iPhone just to refresh system resources.

If none of these work, it could be an issue with your account or a temporary glitch on Fry’s website or app. In that case:
- Try logging out and back into your Fry's account.
- Check if you can add items to cart when not logged in (if allowed).
- Visit Fry's account troubleshooting page or contact their customer service at 1-800-KRO-GERS (1-800-576-4377) for detailed account-related help1.

Let me know what you find after these steps or if you want me to guide you through any of them! Are you mostly using the website or the app to shop?
