Is this the best deal currently available for new memberships?
For $30 meaning it's 60 after getting a $30 Costco cash card back.
That link only gets you $10 back.
try searching online for the $30 link or if you have a Sprint service you can go through the Sprint app and sign up.
I still have my Sprint app from when I had Sprint service even though I don't have Sprint service so I'm able to get all the perks from the Sprint app..
