Marco Arment has Instapaper (iTunes Link) for the iPhone, iPod Touch, and iPad in the iTunes App Store for $2.99 (4.99 – 2 instant savings) for limited time. We are huge fans of this app here at Cheapskat. So much so, that we have given away copies of the app to our readers. $2.99 is not cheaper than FREE, but it’s definitely worth every penny!

Update: Instapaper is also available for Android in the Google Play Store for $2.99 for limited time.

Instapaper saves web pages for later offline reading and optimizes them for readability on your iPhone, iPod touch, and iPad’s screen. Featured by Apple and critically acclaimed by top blogs, newspapers, and magazines!

Great for long articles and blog posts that you find during the day and would like to read, but don’t have the time when you find them. Save with Instapaper, then read later when you’re commuting, in a meeting, or waiting in line.

Need something to read? You can browse articles that your friends posted on Facebook, Twitter, or Tumblr. Or browse the Editor’s Picks, curated by hand from the Instapaper community’s most-saved stories.

Sending to Instapaper is supported by over 150 other iPhone and iPad apps! You can even send long emails to Instapaper to read later.
