A friend of mine mentioned this to me earlier and I didn't see anything about it here so I thought I would pass it along. Tracfone currently has the 16GB Iphone SE for $159, with free overnight shipping. Seems like a pretty decent deal. Looked into whether this can be used on other networks and couldn't find anything definitive, but seems to be a possibility. I'm sure there are those of you here that know better than I.
Click the above link, put in your zip code, and then scroll down to the iphone SE on the page. The original link directly to the phone didn't work.
