They Suck! Their prices Suck! Their service sucks!
Went to the post office with 6 boxes today. Two were turned down because they were too long. Both were about 3 feet in length, one was very light.
I had another three other boxes which they complained they did not weigh enough for the size of the box. 20X20x12. They weighed about 5lbs. They wanted to charge me $18.80 just for the shipment. On top of that charge there was a surcharge due to the lack of weight. Total cost of each box $34.00.
I decided to go to UPS. The clerk told me they would charge me two and half times less than the amount of the Postal Service.
I took my chances. UPS cost for my oversized, underweight boxes $13. No surcharge.
IMO the US Postal Service Sucks.
