As much as I love running, I also like finding good deals and values. I'm not one of those crazy couponing people that buy stuff they will never use or one of those shopaholics who will check out the latest sale to save a few bucks when they could save more money by not shopping and putting that money towards debt. My wife and I are pretty frugal (cheap) and understand the importance of financial responsibility. But if something comes up (especially if it's free) that is practical, I jump all over it.
I use Virgin Mobile for my cellular service. I got grandfathered in on the $25 unlimited text/data plan but unfortunately, it only comes with 300 minutes a month. I've been looking for a app I can use over the network or wifi that doesn't use my monthly minutes. I tried out Groove IP but the quality is terrible. Vonage has a decent app that's free for a limited time right now that can make free calls to any landline or cell phone in the USA, Puerto Rico, or Canada.
You can download it at http://www.vonagemobile.com/. The quality is pretty decent and is definitely worth checking out.
