T-Mobile and Costco have an unbeatable trade-in deal for iPhone XS, XS Max, and XR buyers
The conditions of the deal/s may have changed since the initial publishing of this post.
Apple's "limited time" trade-in discounts for iPhone XR, XS, and XS Max purchases are still available, but although they're pretty hefty by the company's own standards, you can unsurprisingly get much better deals of a similar nature from third-party retailers and major US carriers.
Costco and T-Mobile, for instance, are joining forces yet again on a limited time promotion with an unspecified expiration date that will let you shave up to a whopping $700 off the list prices of the three aforementioned iOS handsets. There are a number of requirements you need to meet, starting with the obligatory trade-in of an eligible device in fully working condition.
The maximum discount is obviously up for grabs for those willing to part ways with new high-end devices like the Samsung Galaxy Note 9, LG V40, G7, Google Pixel 3, Pixel 3 XL, and OnePlus 6T. But you can also discard an older iPhone X, 8, 8 Plus, 7, 7 Plus, Pixel 2, 2 XL, or a member of Samsung's Galaxy S9 or S8 families and you'll still receive $700 back on your iPhone XS, XS Max, or XR order.
Meanwhile, trading in an even older and/or lower-end handset like the iPhone 6s, 6s Plus, 6, 6 Plus, LG V20, G6, V30, V30+, Google Pixel, Pixel XL, OnePlus 6, Samsung Galaxy Note 5, Galaxy S6 series, or S7 series will get you a cool $550 on a virtual prepaid MasterCard. Yup, that's 550 bucks for an ancient iPhone 6 or an LG G6 you can buy for peanuts right now on eBay.
When it comes to strings, there are quite a few attached to this deal. For starters, you have to activate at least two lines of T-Mobile service if you're a new customer or one new voice line if you're already subscribed to "Magenta." You also need to purchase the iPhone XS, XS Max, or XR at full retail price from a physical Costco Warehouse location, attach your trade-in device to the new device order, submit a rebate claim using the promo code "COSTCOAPPLEJUNE2019" on this special webpage, and wait 6 to 8 weeks to receive your virtual card you can then use anywhere Mastercard debit cards are accepted.
