(Although it's less traumatic, therefore less dramatic, than quitting the iPhones...Nonetheless, it's still noteworthy.)
I chose to not renew my Sirius Satellite radio! The subscription ran out yesterday, and while I had negotiated down to $25 for five months, I decided that money could be better used for let's say the much needed eye doctor appointment I have, or electricity, or food, or (almost) a whole tank of gas. All of those things are more important than listening to "commercial free" radio.
A few months ago, I discovered that on Channel 2 "Top 40 Hits" the same songs are playing at almost the exact same time as the free radio station... Then I move to Channel 3 "20 on 20" and again, the same song is playing! If you are taking a long car trip, you will discover the same 2 or 3 hours loop the entire weekend...
Why am I paying for this again? I doubt I will miss it as much as I do my iPhone, but it's just another expense we can live without while we are on our road to debt freedom!
