Redwolf ships via DHL which is extremely fast and very expensive. If you can't find it in country it's an option but you will get slapped with a hefty shipping charge and customs/duty to boot.
My last order was here in 3 days. About $100 usd worth of small items, $26 usd for shipping, $30 CAD for customs/duty.
It was probably a little cheaper still than buying things locally ($70 for a spare Breacher gas tank? I think not Canadian retailers) but not by a whole lot.
