Assuming you used PayByCash?
If so, you should see your NX as soon as the Cash has been received by PayByCash, they may note an estimated time on their website.
i might use the paybycash method if CVS doesn't have them when i check today.
How long on average does it take?
im Guessing More than 11 days :[
PayByCash should take no more than a week at max.
It usually takes 3-5 days for me.
