I ordered a pair of headphones with one day shipping from Amazon.com today (Friday June 19) in the morning. It says it will arrive tomorrow (Saturday June 20th) by 8 p.m. Saturday is not a business day and I am wondering if i will actually be getting my headphones tomorrow even though amazon says i will?

One day shipping time starts after they package and ship the item, which does not always happen on the same day it's ordered, delivery services like USPS do Saturday deliveries, so could be Sat. or Mon.

Track your package.

You will get it Monday at 1:37 pm

Yes, you should receive them tomorrow, they do deliver on a saturday.

Amazon does have weekend delivery, even on Sundays.

Only USPS operates on Saturday, so they will bring it. Wait by the door.

yes you will
