I used up my minutes much faster than I thought I would. Can anyone tell me what is the least expensive way to add minutes to Tracfone? Are there any coupon codes anywhere that I could use? I have heard that sometimes it is possible to get free minutes, but I don’t really know how to do this. I would love to find out though if anyone can tell me how to go about getting them. I can’t afford to spend too much on my phone, but I really do love to talk to my friends a lot and don’t want to have to give this up.
