HobbyLink Japan has just started a new shipping campaign today, where they're offering 20 percent off all shipping costs from now through December 19 at 6 p.m. Japan Standard Time (4 a.m. Eastern, 1 a.m. Pacific). That includes all shipping methods, plus any Ship Now or Private Warehouse orders you might have. And yes, even FedEx is included.
To take advantage of it, just have any of your items shipped during the campaign period. That's it: no codes to enter or other hoops to jump through. And I believe if there's other items on sale, you do get to combine the offers together to save a bit more.
