Wow, great thread. pacme.com is another option (and there are hundreds!). PacMe is a great value when you have a lot of packages, but not so good when you have just a few (vPost is better for that).
For instance, if you build your PC on pcpartpicker and order from newegg, amazon, etc., PacMe will repack the items from all the incoming packages into a single box (or a few) - like playing Tetris to minimize the dimensional weight. Even if you place a single order on Amazon, it still comes in 6 or 7 packages because they drop ship from different warehouses.
