Most mfr's use UPS (ground) because it is cheap. The cost replacing damaged items/dealing with claims vs paying more for an air service , in an accountants eye, is better, because it is less. Getting our orders 99.9% of the time to our customers in the same condition they left in (!) for a few dollars more is, for us. the better option. We ship hifi, not insurance claims! As far as the comment from in that other post about "shipping 100,000 packages with UPS" and finishing them a "reliable service", frankly, so what. Amazon Books ships millions of "books" with UPS and probably finds them to be a "reliable (cheap) service". Do this with hifi and we can tell you the results in advance. UPS (ground) is cheap. They are rough on the packages. You get what you pay for. We mention this because we like people to know there are other ship options. Just because you hear about UPS all the time does not mean they are a good service. We check back up on UPS every so often and find the same results: problems with claims, lost/mis routed COD checks, and damage, damage, damage. FED EX now has a ground service which we will try soon. We hope they will do as well as the FED EX air service, but only time, and shipping HIFI with them, will tell.
