As far as I'm concerned none of them are worth a crap. A few years back we were having a large check sent to us which then had to go to the mortgage company. Everything was time sensitive, so we had the check coming to us overnighted by UPS. This was on a Tues or Wed, middle of the week thing. We got the check the following Monday This cost us a few thousand dollars being so late. UPS said they had an emergency in the Cinn hub which caused the delay. They refused to stand behind their guarantee and they would not even refund us our cost of having it overnighted since we could have paid ground charges and received it in the same amount of time. Another time UPS sent parts I ordered from Dennis Kirk, to the west coast somewhere. This took 2 weeks additional weeks ( a total of near 3 weeks) to get the parts I needed. Dennis Kirk blamed UPS, UPS blamed DK, and even wanted to charge me additional fees to get it to me after all this. You are taking a gamble anytime you enlist a shipping company.....any of them.
