Zelda BOTW Guardian Amiibo - On the hunt!

I've been trying to find this amiibo for weeks now without any luck. Anyone know other stores besides the main 5 (Best Buy, Amazon, Target, GameStop, ToysRUs) that I can look? I know others are probably having the same issue finding it as I am but just looking for any tips for getting one faster. Don't want to pay the ridiculous markup but also wouldn't mind buying a used one for the same price as new. That wouldn't be unreasonable.

If you can help me I'd really appreciate it. Thank you!

off.

Not sure if you ended up getting one, but it seems that Gamestop just got a massive restock of BOTW amiibo.
