Amazon said last month it would cut its shipping time in its prime free service by half from two days to one day, and it seems that the company has already begun to launch its service in some areas.
As shown for example in this multi-characteristic product on the Prime service
(In the picture below), the shipping box has been compensated within two days by Prime service to one day. It seems that this feature has not been circulated to all accounts. There are accounts that have not yet been received by Prime for a one-day shipment.
While Amazon offered free shipping on the same day and a day to prime customers in advance, it was limited to orders over $ 35. But this new service to ship within one day will be on all prime requests, as with shipping service in two days now.
Amazon Finance Chief Bryan Olsafsky has promised earlier that "it will take us a great deal of time to bring shipping in one day to all."
So if you do not have the property yet you may have to be a little patient, but there are some prime customers who have twice as fast.
