Is the Jetson hoverboard dead (or any other hoverboard)? I had it in my cart for $20 but they wanted me to pay shipping. I went to sign up for Walmart+ trial and it went back to full price. Have tried repeatedly in different browsers, but can't get it back down to $20. Was so excited to have a perfect afikomen present for DD. Please let me know if you're still able to replicate it or if it's dead.
