Try USF Holland and Forward Air too. Since they're assembled, you'll be charged at the dimensional weight and not the actual weight, most likely. So if you ship an empty refrigerator box, it might only weigh 15 lb but it takes up the SPACE of something that weighs 300, so that's what determines the rate. The formula used to calculate dimensional weight is length x width x height divided by 194, but Forward Air does the division by 250, which would work out in your favor. If it's possible for you to drop those cabinets off wherever you ship them from, that will save you some cash too.
