T- Mobile.com has a new free refill promotion. For a limited time, most prepaid phones on the site that are priced at $49.99 or more come with a free $30 refill card. The offer is available for both new and existing customers and shipping is free.
The eligible phones are:
LG GS 170 flip phone $49.99
Samsung :) t359 QWERTY slider $50.00
T-Mobile (Alcatel) Sparq QWERTY slider $59.99

Except for the ridiculously overpriced Exhibit II 4G& (Amazon and Walmart sell this phone for under $200!) these phones are all a pretty good deal. The $30 card can be applied toward any T-Mobile prepaid plan, so it's effectively a $30 discount.
These T-Mobile refill deals occur frequently, but they don't usually last more than a couple of days so don't delay if you're interested.
