$400 more than going direct

Costco adds $400 to the T-Mobile iPhone 18 Pro deal

The iPhone 18 Pro "on us" offer is T-Mobile's, and it is the same wherever you take it. Costco adds a $150 Shop Card and a $250 prepaid Visa on top, and waives the $35 connection charge.

Who
Anyone with a Costco membership, new to T-Mobile or already with them. Costco states no membership tier for this — any membership reaches it
Where
United States only, at Costco warehouses and costco.com
ID needed
A Costco membership. T-Mobile runs a credit check for the financing agreement and calls it "qualifying credit", so a thin or absent US credit file can mean a deposit
To qualify
Two different things, and they are not the same test. The phone: "trade in an eligible device in any condition on Experience Beyond" — a broken phone counts. The $400: a port-in, which Costco limits to "AT&T, Verizon, or another eligible carrier"
Trade-in
Any condition, for the iPhone. Costco's Samsung offer beside it asks for "a working phone" instead, so a cracked or dead handset is worth trading here and not there
Paid
$150 Costco Digital Shop Card and a $250 virtual prepaid Visa. Costco prices the pair at "Get $400 in value". The $35 device connection charge T-Mobile bills direct is waived here

Before you sign up

  • The phone is not discounted. T-Mobile pays for it with up to 36 monthly bill credits, so it is free only across three years on the plan. Their terms: cancel the account before the credits finish and "balance on required finance agreement is due", and "bill credits end if you pay off device early".
  • Already with T-Mobile? You can still get the phone by trading one in, but not the $400 — Costco's money needs a port-in from another carrier. Nobody in the thread this came from got an answer to that question.
  • Neither payment is quick and neither is cash. Costco says "allow 16 weeks" for the Shop Card and "14 weeks after rebate submission" for the Visa — and that Visa is "for use at T-Mobile or Costco", not anywhere that takes a card.
  • Sam's Club sells the same T-Mobile offer with a $150 eGift card and $60 a year after. The annual payment needs a Plus membership, which costs $120 a year against $60 for the ordinary one — so the $60 covers the upgrade and little else.
  • The phone is a pre-order. Costco's button says "Pre-order now", so the trade-in and the bill credits begin when it ships, not when you place the order.

Where a shop’s terms turn on visa status, the deal says so — checked against the shop’s own terms, and including the offers that turn out to be closed to people on a visa. That is the part nobody else prints.

The deal itself is a public promotion, and the member who found it earns nothing from posting it. A row in the stack marked as a referral does pay the member whose offer it is, at no extra cost to you, and says so on the row. HelloStamped takes nothing either way.
