If anything have the coupon image file on your cell phone. One time they did ask me for my rewards program ID number or whatever so be sure to have an account. Good luck.
Don't recall these ever being released as a sample. It was being sold on NDC for a while. Best way to prove that it's a sample is to check the box, but there is no box...
They never restocked them but they put them up on accident. There were other colorways up like the all lime women's one too. That also showed as out of stock. Move along.
