Man they sure can be! 4ish years ago I got a Bose Soundlink 30 and 20 systems that run $499 and $299 for $119, and $91 respectively. This wasn't my store, but sitting in my wife's store's warehouse still "shelf displayed" and forgot about. Yeah I still use these daily, especially the 30. Heck I got my old iPad Mini 4 the same way open box haha. I think like $180 at the time. So many EOL deal stories...... Speaking about Best Buy..... they carry travel adapters that adapt the plugs from US, to EU, AU, ect... applications. $25 maybe? That or Home Depot might have an adapter that you can then plug the outlet into.
