Best Buy will give you an iPhone 6 for $1 on-contract if you trade in a working iPhone 5

Last week, we told you that Apple increased the iPhone trade-in value by $15 across all models. Although a welcomed improvement, Apple will only give you $100 worth of credit if you trade in your iPhone 5, which is certainly not the best trade-in value around. If you crave for the iPhone 6 but feel like your iPhone 5 is worth more money, and you also don't want to go through the experience of selling the old handset yourself, you might want to take advantage of a new promotion from Best Buy.
