Lately, packages, even priority ones, take two days to ship.
If I request priority, the package is prepared the next day, and the day after that, it's picked up by Fedex.
If the problem is caused by the high volume of packages and priority requests, I would request Priority Premium if possible.
Perhaps limited to Whale or accounts with frequent shipments, even at a higher cost (instead of $2.50, I'd pay $10, four times as much), but with next-day preparation and shipping.
Thank you.
