I'm trying to buy maze coins, but I constantly getting errors saying "an error occurred while trying to process your purchase". This is on an Amazon Fire tablet. Any help before the event ends?

Unfortunately buying with the Amazon app is hit or miss, they do not always do the conversions correctly. Most times I know it will not work when the $ sign is at the end of the text instead of the beginning. When that happens I usually use one of the other platforms on a different device. I would tell you to report it but reporting it will not help you before the event ends since they are off the weekend. If at all possible you should use another app platform on a different device to make your purchase or if you are tech savvy, sideload the android version onto your Fire tablet.

You see this second one, you can't buy that one?
