On 11/11/17 , Sam's club will give you a $300 gift card when you purchase and activate any Iphone. Plus possible waived activation, see details below.
The email I got says with purchase on installment of any iphone, but the details implies only activation is required.

Installment not available on U.S. Cellular. Subject to all terms of Sam's Club Mobile Secondary Retail Agreement. This offer may not be combined with any other offer promotion.
