My Chat with Amazon CS:
Me: Hi, I just did a promotion where if I posted an answer to facebook and shared it, I qualified for a $5 Amazon credit. The credit however is not being applied to my account.
Veena:promo was expired, hence as an exception aplied $5 promo
Veena:Please allow me a minute or two while I research this for you.
I did the promotion while it was still alive
It said $5 has been credited, but it doesn't show up when I try to checkout.
Veena:I'll apply $5 promotion redit to account.
Veena:Promotional certificate has been issued.
Is there anything else I can do for you today?
Me:So when I go to checkout next, it will show up?
And BOOM... It works.
