Got a couple estimates today to ship some parts (2 boxes) and was in sticker shock. To give an example, one box was 37 x 25 x 11 and actual weight 14 lbs. They put on the estimate 53 lbs billable weight for a cost of $36.50.
I went to usps.com and it says $68 for 5 day parcel post. I reduced the dimensions to see if it would give me a different cost. Narrowed it down to 36 x 24 x 11 and it gave me $17.00. Apparently 1" on 2 of the dimensions makes a difference.
The other box, UPS estimated cost of $33 and usps gave $17.00 for 5 day parcel post.
I am guessing UPS is charging by billable weight and not actual weight? Anyone know?
