If you have been staving off a Samsung Galaxy Tab purchase hoping for some better pricing options, T-Mobile is making the idea a little bit easier to swallow with holiday price drop on the device. What once set you back $399 after a mail-in rebate is now reduced to $349. The $50 price cut carries over to the Samsung Vibrant Galaxy S phone, which sees a drop from $199 to $149. Both deals require the signing of a two-year agreement with TMo. No telling how long the sale will last, so jump on it now if it sounds like these are the prices for you.
