Some Farm Cold store Cider to sell during the summer and pre harvest season. IF you look around you may be able to find Cider pressed on a farm.
Yeah, orchards often/usually freeze some juice to see in the off-season, so you can still pick up some good stuff if you try. That's what I would recommend. Or, at your grocery store, seek out the Simply Apple brand, which is real juice (hazy brown with dark stuff at the bottom) without preservatives. The preservatives in other apple juices from concentrate can slow or prevent proper fermentation... and real juice tastes a lot better anyway, and isn't terribly expensive.
Be aware that no matter what yeast you use, fermentation will take at least a month if not two months. Cider ferments a lot more slowly than beer. So if you want to drink it this summer.... it will be very late summer even if you start right away.
