It's quite funny actually. I just last week completed my collection of Smash Bros Amiibo, at least until the next wave is out. It took a lot of time, and I had to result to importing a couple from Japan like Dedede and Lucario, for a about double the cost. Not a big deal and I don't regret it, but the second I complete my collection the restocks start happening hahah.
It used to be I could walk into my local GAME store (Stirling, Scotland) and they'd have 5 Amiibo total, mostly Link and DK and nothing worthwhile.
I walked in today, and they now have about 80 in stock, and it's fucking marvellous to look at. They had multiple Shulks, Dedede, Lucina, Ike and more in stock today. It was glorious, in all of my UK Amiibo hunting since day 1, I've never seen anything like it.
If people were hesitant to start Amiibo collecting, it seems it's not too late. In fact, it might even be the best time to start.
