The retailer is selling the 16GB iPhone 6S for $1, while also throwing in a $200 gift card if you trade in a working iPhone 5 as part of the deal.
If you're on the fence about whether to take advantage of the weekend sale, Best Buy's got one more thing you should know about it. If you decide to also trade in your old phone, if it's an iPhone 5 or newer, Best Buy will also give you a $200 gift card. It's basically like getting paid to get a new phone, which is amazing.
The only potential negative to this whole situation is if you have to actually visit a Best Buy store. Thank goodness you can just shop online.
