We have been seeing the same thing. One order today was 7 days and everything else was 8 days (one of which was a Zone 4).
With AHT and SSA enabled, the above is what we see.
- Haven’t had a business order so interesting on the calculation.
- Estimated transit is greater than USPS 2 to 5 day and basically means every order has an extra day transit due to having a Sunday (and or Holiday) involved.
- Have no idea why there is a promise extention when 100% are delivered on time without a promise extention.
- Our promised delivery time is about the same as when we didn’t use AHT and SSA (within one day).
- Our promise gap is also about the same as when we didn’t use AHT and SSA (withing one day).
- Our actual delivery time is now one day longer than when we didn’t use AHT and SSA.
Since most of these have floated up over the last month or so, we think it might be a reflection of Amazon playing with how having automated handle time capacity will / can impact the numbers.
Transit time for probably at least the last month has been either 7 or 8 days on our orders. We even had a Late Delivery Risk for a USPS Ground Advantage that was delivered 2 days before the estimated deliver by date.
If we could teach Amazon to think outside the box instead of trying to squeeze everyone into the same shoebox, how much easier and more efficient it would allow our Amazon business to run.
