Here is the reply I just received from SI. My contact is now forwarding any inquires to the PR Dept. I guess this is a stemming from some of the communication they have received around this product.
Hi Andrew,
So great to hear from you and I’m glad to hear you’re close to completing the collection.
You will find Ebayer and Minute Mud at Walmart. Keep a lookout, they’re there, I promise!
As for the Gold Windhex, this is a “Fuggetaboutit” Rare – the most rare of three tiers of rare in the series 2 collection. I am SO excited to hear someone got it. It truly is a special rare, and not many will come across this while collecting!
