I recently placed an order with amazon for Simpsons Season 3 at 29.24 after Share the Love. I had over 30 dollars in Gift Certificates so at the screen at checkout it said I didn't have to pay any money.

Going into my account and looking at the order summary it now says that I have to pay 3 dollars and change and the share the love discount is no where to be scene. Is this an error or just standard Amazon operating procedure.

Any info will be appreciated.

There is a current thread going with Amazon STL problems located here with more information. I think you should call customer service for help. They will probably issue a refund for the lost credit. If the order didn't ship yet try making an edit to the order like changing the shipping options. That seems to restore lost STL credit.

I found out that you can go to your order, then change the shipping option to something else, and then change the shipping option back to your original pick. When I did this, the Share The Love that disappeared before, reappeared again. Try it and see if it works for you too.
