My prime membership is listed as expiring today.  That's fine, I was going to renew today.  But I wanted to add a few prime items to my cart so as to make only one check out, but they aren't showing at prime prices, and more to the point, I can't use the Prime renewal coupon.  If "expires on July 18" means that today my account is expired, then it should have read "Expires on July 17."  If Expiration is based on the time of day I purchased the Prime Membership, then the time should be listed too.

I'd post this in the prime membership forum, but since my prime membership has expired, I can't access that to ask for help or advice.

 

And I'm in the same Time Zone as the Renderosity Servers (unless they've been moved recently) so it's not a matter of the different time zones catching me off guard.

 

Edit to add: and I checked my account history, and I purchased my membership last year on July 19, so now I know it's shorting me a day.
