Same here. Kept refreshing, finally got the pre-order around 12:20 EDT, added to cart, and then Checkout never worked. Kept reloading, Checkout, nothing. After doing this for 20 minutes it finally it kicked me out, wanting me to log back in (which in itself took another 5 minutes), then said none were available within 250 miles. I can't believe in 2020 we're still dealing with these problems of websites crashing and loyal customers not being able to pre-order. They need a better process.
