Ok, since I bought mine, I can share this deal while they last. Back when the GoPro Hero 4 was due to be announced, Sam's club put together some bundles of the GoPro Hero 3+ Black at a highly reduced price, like $120 less than the camera alone and it came with a dual battery charger, second battery and remote.
Well, with the new Hero 5 looming, Sam's has done it again. The top of the line GoPro Hero 4 Black runs $499 every where since release, most places have discounted it to $449 including the GoPro website. Sam's has the Hero 4 Black, floaty back door, Floaty stick, a pile of mounts, Dual battery charger and two batteries and a tiny 16GB Sandisk Extreme for $379!!
That's still a ton of cash, but a great deal without having to shop Ebay for a used one in hopes that it still works. I could not contain myself as I had just replaced my 3+ Black with a Chinese knock off. I just could not justify $500. This cam is incredible. Now is the time to buy for those on the fence. If your local Sams does not have it in stock, they do free ship to store in a couple days.
Good luck!
