The full refund applies to cards purchased in stores, from the RadioShack website, or from authorized sellers such as Safeway. Claims also count for cards either purchased by the card holder or as a gift to the card holder, the refund website said.
Even if you don't know the balance of your card, you can submit a claim, according to the website.
The claims process is part of RadioShack's bankruptcy settlement with more than 20 states and the District of Columbia, first announced in September. The tech retailer has been staging a rebound after shuttering many locations since it filed for bankruptcy in February.
There are exceptions to the gift card refund policy, the website said. The full refund may not apply to gift cards issued as part of an exchange, customer service dispute or warranty refund, for instance.
If your heart still yearns for a RadioShack device, the company is working to create a system that will allow gift cards to be redeemed at the remaining stores, although the option is not yet available, RadioShack said. Still, it will apply only to RadioShack-branded products and can't pay for more than 50 percent of an item's purchase price under the new system, according to the website.
