HBO is offering a free preview this weekend so that even people without an HBO subscription can catch the Season 6 premiere of Game of Thrones live. But for non-subscribers who want to play catch-up before then, there are a few ways you can do so online — if you're willing to cough up some dough. Like all current HBO shows, Thrones is unavailable on Netflix, but here are your other options:

1) HBO Now: HBO's standalone streaming service is available on basically any device that connects to the Internet — including, as of Thursday, Xbox One and Xbox 360. (In addition to the free preview, the Game of Thrones premiere will also be free for all Xbox users from Monday, April 25 to Thursday, April 28). An HBO Now subscription, which includes access to HBO's entire library of movies, as well as past and present TV series, costs $15 per month.

2) Amazon Video: The first five seasons of Game of Thrones are all available via Amazon Video, with individual episodes for $3.99 and entire seasons from $14.99 to $24.99.

3) iTunes: The first five seasons are also available on iTunes, at the same price points as Amazon Video. iTunes also offers fans the option of buying Seasons 1 through 5 together for the (very slightly) discounted price of $88.99.

Game of Thrones Season 6 premieres Sunday at 9/8c on HBO. How will you be watching?
