I witnessed that issue, I re-submitted payment after 5 attempts and got thru. PayPal option was not showing up for me as well.
Checked your online bank statements to see if you've gotten charged ghost orders.
ADC shipping departments backed up
"Order Status: In progress - Order confirmed, waiting to be packed"
Chose the free shipping option, out in cali. Glad i'm not the only one with this issue.
Got thru a size 9. Order email confirmation received at 8:29am PST
I selected 'free' shipping option. L on my end.
Also got a size 7 from confirmed app.
I know a few NT'ers already have their pairs shipped out.
