Iphone 5s blavk friday walmart

Regarding the walmart black friday deal on the iphone 5sWhen you buy the iphone 5s can you put the walmart gift card towards buying the 5s? Yet you, must buy the 5s first so how do you use the card? Its all very confusing to me i'm probably over thinking it but please help, me with this.

No Einstein, you don't get the gift card until AFTER you finish the transaction of buying the phone.
