What is the difference between UPS Ground and UPS Ground Saver?
Ground Saver is the slower economy tier: it moves through the UPS network and can hand off to USPS for the last mile. On several boxes here it undercut standard Ground by a few dollars for a day or two more.
When is UPS cheaper than USPS?
Heavy and bulky. From about 20 lb up, UPS led every comparison on this page, and on the 50 lb carton it was the only carrier under $50 to Chicago.
Does UPS charge for residential delivery?
Yes. There is a residential surcharge, and it already sits inside every price quoted on this page, so nothing new appears later.
What is the UPS dimensional divisor?
For daily-rate accounts it is 139. Work out the carton's volume in cubic inches, divide by 139, and UPS charges on that or on the scale weight, whichever comes out higher.
Where does UPS stop taking a parcel?
Past 150 lb, 108 inches in length, or 165 inches in length plus girth. Past those limits it is freight, and SMKlog puts it in front of a person rather than issuing a parcel label.
