After four years on air, Entourage fans will finally be getting another way to watch the cable series.

As of today, Seasons 1 and 2 of the comedy have already been available to iTunes users. The third season will hit the online market on August 18; the fourth arrives the week after that.

If you’re hoping iTunes can spare you from subscribing to HBO, you may be out of luck. If you want to watch your episodes in a timely fashion, you’ll have to cough up the dough. While Season 5 will eventually be available for download, it won’t be placed online until the DVD’s release.

Mark your calendars for the crew’s return on September 7.
