T-Mobile is offering a rare BOGO deal on phone cards for this weekend only. Buy one prepaid phone card and get a second select phone card of equal or lesser value for 10% off. Eligile phone cards include some of the most popular services, including T-Mobile, AT&T Wireless, Verizon, Boost Mobile, Cricket, Tracfone, and Simple Mobile. Phone cards are available in denominations of $10 all the way up to $200. Depending on where you live, local phone fees may apply.

Buy One Get One 10% Off Select Prepaid Phone Cards

Stacks with Target Circle 5% discount

This deal is even better if you are a Target Circle Cardmember because it stacks with the flat 5% discount you get on Target purchases (prepaid phone cards are eligible). If you combine the two discounts, you’re saving nearly 10% off the entire order, which is usually as good as you can get when it comes to prepaid card discounts.

The Circle Card is Target’s own branded credit card that gives you 5% back on most of your Target purchases. There’s also no annual fee. One advantage that the Target card has compared to other cashback equivalents from Amazon, Best Buy, or Walmart is that this is not a “cashback” or “rewards” offer. You literally get a 5% discount applied to each and every Target purchase on the spot. No further purchase or waiting is necessary.
