I use Skype for most of my international calls at home (such as the the bmi Diamond Club call centers in India, for which there’s no U.S. number), the quality does vary but it does the trick. I also use it to call from abroad, when I’ve got internet connectivity. (When I’m roaming around I use an unlocked cell with a SIM card from OneSimCard.com which suits my needs in many countries.)
CollegeBudget.com has $20 Skype Credit for $10, one per person.
Your $10 purchase yields a $20 e-gift code that can be deposited at skype.com/voucher.
The site says the voucher expires September 26th, but then in the fine print says it must be redeemed by September 30th. I assume one should redeem it right away, and that the funds deposited are treated as normal Skype credits and expire (or do not) under normal Skype rules.
This deal is only available until 3am Eastern.

Update: I happen to have a .edu e-mail address, so didn’t realize the site was specifically looking for that. Joey, who sent the deal, writes: “It says for students but just link a facebook account and you’ll be fine, I just did it.”
