If you haven’t been lucky enough to find them at your local brick and mortar Toys’R'Us store, you can now order the polybag 30005 Imperial Speeder Bike online. Unfortunately, there’s no free shipping and you’ll probably end up paying tax. Not worth the cost if you’re just getting one or two. But as an add-on, or if you get like, say… 999, then it’s probably worth it.
Thanks to that guy for the heads up.
