Hello! I see that you're trying to purchase puzzles on Jigsaw Puzzles Epic, but you get a message saying "offline," and the transaction won't go through. Let's figure this out together.

First, just to clarify:
- Are you connected to the internet on your Kindle device when you attempt the purchase?
- Is your internet connection stable?
- Have you tried restarting your device and then attempting the purchase again?

Sometimes, the app may say "offline" for purchases if the device isn't properly connected to the internet or if the store server cannot be reached.

Here’s a simple step-by-step approach to resolve this:

1. Check Internet Connection: Make sure your Kindle is connected to Wi-Fi or cellular data and that the connection is stable. Try opening a webpage in your browser to confirm.

2. Restart the Device: Turn off your Kindle and turn it back on to refresh network settings.

3. Update the App: Verify that you have the latest version of Jigsaw Puzzles Epic installed from the Amazon Appstore. Sometimes outdated apps can cause purchase issues.

4. Clear Cache/Data for the App:
- Go to Settings > Apps > Jigsaw Puzzles Epic
- Tap on Storage
- Clear cache first, and if needed, clear data (note this may remove saved preferences, but not purchase history).

5. Verify Account and Payment Info: Ensure your Amazon account on the Kindle is logged in properly and the payment info is up to date.

6. Try a Different Purchase Method or Content: See if you can purchase any other puzzle pack or in-app item to isolate the problem.

If after these steps the app still shows "offline" for purchases, it could be related to the app's connection to the purchase server. In that case, you might want to check if there's any known outage or contact the app’s support team for help. Also, some users had success by confirming that the purchases appear in their Amazon orders and then restarting the device to sync properly4.

Could you please let me know which of these steps you have already tried, and what happens when you try them? That way, I can assist you better with the next move.
