Walmart has a gigantic incentive for an iPhone or Samsung Galaxy smartphone upgrade for Black Friday sales, offering up to $450 in eGift cards.
If you purchase and then activate an Apple iPhone XS or Samsung Galaxy S10, Galaxy S10+, or Galaxy Note 10+ you'll receive a $450 eGift card from Walmart. If you go for the slightly lower-end iPhone XS Max or iPhone XR you'll get a $400 eGift card, while the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, and Samsung Galaxy S10e and Galaxy Note 9 will all see you with a $300 eGift card.
Walmart is running the deal between November 28 and December 1, so you'll only have a few days to make your decision. The Black Friday prices apply between those dates with the varying levels of eGift cards, are available in-store only, and require a new phone plan through either AT&T, Sprint, or Verizon.
