I'm on vacation and only brought my iPad with me. I just read about an app on the Mac App Store that is normally $15 on sale for free. Is there any way for me to download it while away from my Mac? I have access to an iPad, iPhone and a windows PC.
Do you have any remote software on your Mac like LogMeIn? If not, you won't be able to get it and I'll bet you grab the free version of LogMeIn when you get back.
That sucks. Well, at least you're sort of doing it right. Is anyone available at your house that could download it for you? That's about all I can think of other than going to an Apple Store and downloading it under your account so you can re-download later.
