We know it be frustrating to change your mind after giving a tip or unlocking episodes of a series that turns out to not be your favorite - especially if you're just trying to grab a free-timer episode or save up bonus coins - but unfortunately we are unable to return coins that are tipped or used to unlock episodes.
We've tried to make using coins to unlock episodes and tip creators easy and intuitive, without introducing unnecessary steps to get in your way. This has worked very well in limiting accidental spending for most people.
Because episodes unlock instantly and tips are immediately added to the balance of the creator (the artist, author, or publisher), we are unable to re-lock episodes or un-tip coins. We see it as unfair to the creators who received those tips, as well as to other readers who unlocked and read the episode by buying or earning coins. To us it's like taking money back out of the tip jar at your favorite cafe, or returning a book after you read it.
I spent real money on accident!
If you accidentally purchased coins in Tapas via Google Play or iTunes (i.e. spent real money in the Coin Shop) or had another problem with a transaction and haven't spent the coins yet, let us know!
