When I saw this, I should've immediately posted it to my blog, but I didn't. I hope it's still available!!
Check out the details on this Sprint plan. It's $30 a month and it includes 500 minutes, nights start at 7 PM and you get free text messages and Sprint vision!! I think you can get another $50 off. Read his "Deals" section.
Jump on it though. It may run out soon!
