Seemingly not content with its $25 gift card deal, Best Buy has undercut itself and is now offering $50 off the iPhone 5. What that means is that you’ll only pay $149 up front for the base-level iOS-powered smartphone on a two-year plan. That also means that the 32GB and 64GB models will cost $249 and $349 respectively. If you took up the company’s offer for a $25 gift card last week, you can return it and get $50 off instead. If you used the gift card, Best Buy will still give you a $25 discount off the price of your original iPhone 5 purchase.
