There are many reasons to pick up a Google Play gift card. Whether someone's birthday is coming up, you don't have your own credit card, or just you want to force yourself to stick to a budget, gift cards can make it easier to scratch a Google Play itch. Google's gradually rolled out availability to a handful of countries around the world, and it looks like the latest locale to make the list will be Hong Kong.
As the timeframe is listed as "coming soon," we can't tell you when to start looking for gift cards. That said, we do at least see the available increments. Cards will likely go for 200, 500, and 1000 Hong Kong dollars when they eventually hit store shelves.
