Why was your first delivery May 5th? You skipped your actual first delivery?
I subscribed on March 23 with the first delivery to be by May 2d (the only option I was given at the time. I think the cut off time for a current month delivery are orders placed before the 21st or 22d of each month).
On May 1st I received email "Your subscription item Nielsen-Massey Vanillas Madagascar Bourbon Vanilla Bean Paste, 32 Ounce is not currently in stock. The item is being restocked, but your scheduled delivery has been delayed. We apologize for the inconvenience."
And another email on May 5th saying "We encountered a problem with your delivery of subscription item Nielsen-Massey Vanillas Madagascar Bourbon Vanilla Bean Paste, 32 Ounce. We tried to resolve the issue, but were unable to do so in time for your current delivery. This order has been canceled. We apologize for the inconvenience.
We plan to process the next delivery in your subscription on schedule."
