If you don't want to wait until November 23 for Walmart's $300 gift card Black Friday offer on a top iPhone or Galaxy in-store activation, Sam's Club has you covered. The club retailer will hold a one-day event on Saturday, November 11, where you can get the $300 off the price of a Galaxy S8, S8+ or Note 8 in the form of a gift card, or $250 off the latest iPhones, including the X. Given that the promo will include a waived activation fee, which is a $40 value, your Sam's Club memebership card won't be issued in vain.
The fine print is that there is no fine print, as the carriers and installment plan offers will depend on your particular location, and are available in-store only. Sam's Club will give you the $250 or $300 gift card right then and there upon activation, though you can't use it for the service or the phone, just get something else in the store.
The waived activation fee will be refunded to you in the form of bill credits, and the line of talk and data service you sign up for has to be in good standing for at least 90 days. Not a bad deal at all, if you are eyeing a new flagship phone with a service anyway.
