If your in-app purchase doesn’t show up, doesn’t work or doesn't display a price (showing you $0 instead), please check that you have a working and active Wi-Fi or mobile data connection. Also, try force closing and restarting Bowling Crew. There might be delays in displaying prices on the part of Google Play, and you may have to wait for a while to see the price.
