I am a e commerce seller and I send my boxes via many courier service. Some parcel I send from this courier service. And I like something and dislike something.
What I like
Pick up response is good.
Deliver so many pincode.
What I don't like.
They take so many days to deliver. If you are seller then your customer will not happy with this.
Delivery Charges is slightly higher.
Overall if you are e commerce seller then you will face delivery time issue.
