At this point in time I would just get the phone somewhere else, who knows when Sam's club will get it. Best buy was offering a $100 gift card, don't know when that ends, plus Samsung has a pretty good promo going on right now, free sd card, ear buds, and 6 months Netflix free.
Edit.. Just looked on best buy website and you get $150 gift card plus you can sign up for Samsung promo. You wait for Sam's club chances are the VR promo will not work for you and far as I'm concerned this new promo is better deal anyway. Gift card, I just looked at the Verizon version but imagine all the carriers are the same.
