It's probably very different here than in the US so I'm guessing it can't be compared, but I really hate UPS here, they suck bigtime. Extremely difficult to deal with, difficult to get to hold for pickup, never calls before delivery and I swear sometimes they don't even try to find the house when they update tracking with delivery attempted. Always some kind of problem with them. It's a pain everytime I have to use them, and I'm so glad SS doesn't use them internationally. FedEx is so much more reliable and effective for me.
That sucks. I hate it when I need to sit in front of the window just to be sure...
