I wish Anker sold direct on their site (and shipped to Canada) because searching for Anker products on Amazon almost invariably turns up a sponsored, cheap knock off and an "Amazon Basics" product as the #1 and #2 results. I can't imagine they're happy about that either.
Anker availability in Canada is weird. There seems to be no pattern as to whether a particular item won't be available on amazon.ca, and whether the amazon.com listing will be eligible for shipping to Canada. I've contacted Anker a couple times about specific items, and they've just given non-answers both times.
