Well I was right, the Pixel Stand promo is working out the same way for me as the free Home Mini offer went last year. I saw in another thread that a couple people got notifications that their Pixel Stand had shipped, and they were shipping from Memphis TN, which is where Verizon ships from. So the Verizon reps I previously talked to were mistaken saying that Google was sending these free stands out. I also called Google as well just to be sure and just like last year, they questioned why they would be the ones to issue the stands for a Verizon only promo. So I called Verizon back and explained the situation, and they did some checking and ended up charging one to me and then issuing me a credit for the order. That was on Saturday, and while I was typing this my Pixel Stand was delivered.
Long story short, Verizon is the company sending these out, not Google. If you haven't received one yet or seen a shipping notification, call Google and explain the situation. If they keep trying to pass the buck keep on them. If they're going to offer a promo to get you to buy something, then they need to honor that, or stop doing promos.
