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, residential delivery carries a surcharge, and it is already inside the prices quoted here — there is no separate line added later.
What is the UPS dimensional divisor?
For daily-rate accounts it is 139: length × width × height in inches ÷ 139 gives the dimensional weight, and UPS bills the greater of that and the scale weight.
Where does UPS stop taking a parcel?
Past 150 lb, 108 inches in length, or 165 inches in length plus girth. Beyond that it becomes freight, and SMKlog routes it to a human review instead of a parcel label.
