I've considered that multiple times actually, but I've held back just because I went through a spree of buying amiibo cards and doing some trades on other websites and almost none of them went well because
unfortunately I like my cards to be in mint/near mint condition, and I had multiple bad trades/transactions. Almost none of my cards came in the condition that was promised despite taking
numerous precautions. I was even told that my standards for mint condition were too high (which I don't understand because mint means mint?) and I just like, kind of gave up after a while. OTL
I guess it may sound stupid to some other people since I think most people are casual collectors, but those experiences basically shattered any trust I had with buying or trading, so I've come to just buying fresh packs instead.
