I deal with logistics at the small company I work for, and deal with UPS all the time and am actually thrilled with them. Good rates certainly help, but the customer service (at least for business customers) has been far better than Fedex, for example. We get the same driver every day as well, which helps a lot too. We don't really deal with Amazon couriers in a business sense, but I find them a nightmare to deal with personally. Since I don't know ahead of time how it will be shipped, I can't make intelligent choices about where to ship to. If I ship home, it shows up during the day with a legacy courier; if I ship it to my work, it ends up with one of those Amazon couriers that just toss the packages at the front of the building in the middle of the night or on weekends. Neither option is great, and it's a major factor in me using Amazon less now.
