There's never been a better time to buy a T-Mobile myTouch 3G Slide When the Slide originally launched at Wal-Mart, the price was set at $199 with a 2-year contract. Now the world's largest retailer has cut that price down to a more reasonable $129.99 (T-Mo News).
This price is for new activations with a 2-year contract. Existing users that are making an upgrade may do so for $139.99 with a 2-year extension. Buying the phone unlocked will still set you back a painful $499.99.
