I think it is a great deal. I still don't understand why it is at such a low price for a brand new phone but I am happy it is. $199 for a new iPhone that doesn't require a new line or tie me into a contract is nice. When I saw it on Slickdeals in mid-April, some people on there were surmising that the trade-in value months from now will be the same as this purchase price. Going from a 6 to this SE will probably be a big improvement. I have a 7 and am now considering getting this before the deal expires.
You might need to be patient dealing with
Walmart though. If I remember correctly, our shipment was a day or two late. Communication and delivery is not Walmarts strong suit.
